Lil IHRA classification help please!! Newbie Alert!
 

Hi guys. Very long time lurker but very new to S/SS racing. Here is what I have. Got my two little buddies racing JR's and we are/have been loving it. Problem is my 15yo is outgrowing them rapidly so I'm looking to get him something lined up in a big car. I don't want to go the big dragster route. I want to start him out in a footbrake car that I can let him beat up all weekend yet still run the divisionals when we travel. We are primarily an IHRA family. I also want to get into something we can gradually build into a higher class car as he saves/earns parts and pieces and hopefully get him a nuts and bolts lesson at the same time. Im waiting to take delivery on a 93 Z28 that is currently a very basic almost stock footbrake car. I want to turn it into an IHRA purestocker and eventually make it a crate motor car.

Here is where my question begins. I have tried to figure out which class it will fit in and I cant find the IHRA classification guide. I used the NHRA classification guide and it looks like it will fit into either D/PS or E/PS(???). I found 275 hp and a shipping weight of 3234 lbs (auto/coupe). The NHRA sheet is confusing to me tho, is the factored HP 346? And the class break is 9.35 (so C/SA?)? So at 346 HP the min weight will be 3114 (346 hp x 9.0) plus 170 for 3284lbs for an NHRA/IHRA legal car??

My main question is how does this pertain to the IHRA pure stock classes? If I follow this using the NHRA factored HP it would fit into B/PS but that doesn't seem right. I've seen some others running similar combos in D,E, or even F/PS. If I use the factory 275 it fits into either D or E. I spoke to a local this weekend with a vette with an LT1 that runs E. HELLLPPP!! LOL!

Thanks in advance!

PS I assume its similar in Crate Motor? Advertised crate HP x whichever class weight break you choose + 170 lbs??

Re: Lil IHRA classification help please!! Newbie Alert!
 

I believe that the IHRA has the LT1 at 315 HP for Pure Stock. You might want to give them a call to check.

Re: Lil IHRA classification help please!! Newbie Alert!
 

Kenny:
Welcome to the board.
As posted above, you might want to contact Mike Baker @ IHRA for the latest factored h.p.

My Pure Stocker ended up being factored lower than a regular Stocker 302 rating of the same year. :)

I just wished IHRA would post their latest factored h.p. ratings for each combo on the net.


And yes...it's factored h.p. times class weight break plus 170lbs= minimum race weight.

Re: Lil IHRA classification help please!! Newbie Alert!
 

The information is out there, you just need to do a little searching to find it!

Here's a link - http://www.ihra.com/component/k2/itemlist/category/208

The way the listings have been updated makes locating the right entry harder, but not impossible. If you use a "find" command in your web-browser (Firefox uses Ctrl+F) you'll be able to locate the most recent updates from the list, instead of having to scroll the entire document.

Of course, as mentioned previously, a call or e-mail to the IHRA might also be a good idea!

Best of luck with your new project!

Re: Lil IHRA classification help please!! Newbie Alert!
 

In Pure Stock the LT1 is Rated at 295 like my Car...In Stock the LT1 is Rated 299...
Your cars has an Aluminum Head and my Impala an Iron.
Both are allowed the F-Body Cam.

FWIW contact Mike Baker at IHRA to confirm..

Corbitt Marshburn has a 93 LT1 Camaro and it is set up as B/PS.
Add weight C/PS

Bullet have a great and legal Blueprinted Grinds available

Hope this helps.

When you finish the car send me a Picture for the Pure Stock PhotoGallery

Re: Lil IHRA classification help please!! Newbie Alert!
 

Lew I did do some searching! I found the page you linked me to! It doesn't say anything about a 93 LT1, just 94-97. They are slightly different. THANKS!

Thanks for the help guys. I will get ahold of Mike Baker to confirm. I'll send you some pics soon Dan. Hope to debut it at Lakeland next month if I can get it under the index. Actually gonna debut it at Jackson SC for the Div finals next week, it'll just be in bracket trim, not a Bad ***** Pure Stocker!!

Re: Lil IHRA classification help please!! Newbie Alert!
 

Lot of cool mods..
Contact Bryan Herter for a Tune.
Going to put in a new YankPT4200 Converter in my Impala soon.
Pulling out the YankSS3800.

D

Re: Lil IHRA classification help please!! Newbie Alert!
 

Thanks Dan. If you decide you wanna sell the Yank 3800 lemme know. I need to start getting this thing ready asap.

Re: Lil IHRA classification help please!! Newbie Alert!
 

Wow sure...Need to get car to a tranny builder.
Will try sometime in October.
Where do you live?

Re: Lil IHRA classification help please!! Newbie Alert!
 

Florida, West Palm Beach area. I am praying the rumors are true reguarding us and IHRA. We just got one more new track and one that might switch over. If that happens we spose to become our own division with 4 doubles. THAT would be awesome!

Plan on building another PS when my younger son gets done with JR's and gradually make em both either into crate motor or legal stockers. Honestly I am very excited about this project. I always wanted a class car just couldn't bring myself to pull the trigger. I have raced S/G, Top Sportsman, and fast doorcar stuff for years. Even ran outlaw 10.5 and Heavy Street some. LOVE the heads up stuff, just couldn't bring myself to do it when it started getting really outta hand.

Re: Lil IHRA classification help please!! Newbie Alert!
 

Have you purchased your car yet? Corbitt is selling his on racing junk and the price is right. You couldn't build it for what he is asking and it already has a 12-bolt and some nice pieces. If I'm not mistaken too it runs under the index so it's turn key. Those are great cars as you can easily stay in Pure Stock while you learn and then "step-up" (not my idea Dan) to crate motor or FIA. Corbitt is in Eastern NC so it wouldn't be a horrible tow plus you could stop at Sonny's BBQ on the way. Boy, I miss those!!!

Scott

Re: Lil IHRA classification help please!! Newbie Alert!
 

Thanks Scott, Already have a deal, just waiting to take delivery. I looked at that car, nice piece. I'm hoping to be under the index for 4-5k total investment tho. Looks like it shouldn't be a problem.

Re: Lil IHRA classification help please!! Newbie Alert!
 

Might wanna have a look at this. https://www.racingjunk.com/Stock-Sup...potential.html

Re: Lil IHRA classification help please!! Newbie Alert!
 

That's the one I was talking about. If it wasn't half way across the country I'd buy that one for me let my wife drive the Corvette. Those cars are great platforms Kenny and yes the IHRA Pure Stock indexes can be achieved without breaking the bank. F-body parts are much less expensive than some. A good set of headers, converter, gear and lightweight wheels with sticky tires will get you there ... Also get a nice tune and lose some weight by ditching the AC, smog equipment, etc. Those have always been one of my favorite body styles for Stockers.

Scott

Re: Lil IHRA classification help please!! Newbie Alert!
 

I can assure y'all the car that Corbit has is VERY NICE. I have seen it personally and can vouch for a very nice car with the dad and son being very standup people. If I wasn't knew deep in my car I would love to have his to let my wife start out racing.


You can't go wrong with his car.

Re: Lil IHRA classification help please!! Newbie Alert!
 

Hey Kenny..
When you get close to finishing the car.
Send me a Picture for the PhotoGallery..

WOW the whole state of Florida going IHRA.
That would be awesome..

Kenny my work email is danfahey@dansources.com

D

Re: Lil IHRA classification help please!! Newbie Alert!
 

Yes, Corbitt and his son bought my first bolt-on Impala SS many moons ago when I lived in the mountains of NC. Great guys! Colby was just a baby then ... Corbitt talked to me about the Camaro and even without seeing it I'm sure it's very nice and for the money you won't go wrong. Again, if I wasn't 1000+ miles away we'd pick it up. That would make a great entry level Stocker for someone.

Re: Lil IHRA classification help please!! Newbie Alert!
 

You got it Dan.

Thanks guys. Im getting this car for $2500 with some bolt ons. Its going 8.90-9.0's already and the D/PS index is 8.50. Luckily I have several buds racing these cars so I already so I have some parts lined up. Got skinnys on the shelf and just bought some rear wheels off a fellow Classracer dude today. I have a good bud who is a computer car guru w/ a chassis dyno close by too. This oughta be fun! Pretty good starter car for a kid. Course dad will shake it down till next April when he turn 16! :D:D:D

Re: Lil IHRA classification help please!! Newbie Alert!
 

PS I can see this will be the start of my downfall! LOL! My bucket list car is a 66-67 Chevy II stick SS'er. My favorite was the old Mike Thomas Caliber racing deuce. I have a 325hp 327 ratholed away and even had a Jerico on the shelf at one point.

Re: Lil IHRA classification help please!! Newbie Alert!
 

I've know Corbitt for a while and about a year or two go I met Colby and we immediately became friends. Really good people for sure.

Of you do buy the car I can deliver it ;)

Re: Lil IHRA classification help please!! Newbie Alert!
 

Kenny, As Daren and Lew posted I believe the current hp for a 93 Camaro LT1 is 315 making it a natural C/PS. Min wt is 3320.

Scott and CJ. Thanks for the nice words guys, but unfortunately, there will be no commission. lol

Good luck with the build Kenny. Pure Stock IMO is the last, affordable, entry level category of class racing. Hopefully IHRA will continue to offer it for years to come.
If you need another car for your other son, I know where you can find one.

Corbitt

"Pure Stock IMO is the last, affordable, entry level category of class racing. Hopefully IHRA will continue to offer it for years to come."

Right on! I love the P/S and Crate Motor concepts. Keeping it affordable, CRAZY!! LOL! Plus these both make a great platform for a double duty car. I would hate to beat on a good NHRA legal motor to bracket race it on off weekends.

Thanks Corbitt!

Re: Lil IHRA classification help please!! Newbie Alert!
 

My 1995 Impala SS is no Dime Rocket..

Have at least $20,000 invested over the last few years.
Mostly improvements to keep it functional for racing and street.
Includes new interior, paint, suspension.
Owned it since new..changes were to make the car safe and reliable.
Car has 197k and need to drive it to the tracks

IT does have Jeff Warren built engine.
Helps racers know it was built legal.

IMHO it is just as expensive order a new complete Moser Rear Assembly.
Then adding new gears, posi, axles and longer studs separately.

Dan

Re: Lil IHRA classification help please!! Newbie Alert!
 

Exactly but I don't know that the Crate Motor cars haven't slipped into the land of big dollar engines. I don't speak from experience but believe they are just as costly as running an NHRA class. Our Pure Stock has the stock, unmolested (other than a Bullet cam) 53,000 mile LS1 and should go a second under in good air. We can also drive it anywhere we like and aren't afraid to bracket race it weekly. Is it a cheap car? No, but it's what we chose to build because no one else had one. We like to be unique. :D

Re: Lil IHRA classification help please!! Newbie Alert!
 

Any idea why Turbos aren't allowed in Pure Stock? (Buick GN)

Re: Lil IHRA classification help please!! Newbie Alert!
 

I hear both you guys. Luckily I have some buds down here that are already racing these cars and have extra parts laying around. The rear end parts I need I can get for pennies. I do plan on a strange or moser 12 bolt but down the road. I've been told I can make the stock 10 bolt live pretty easy as I'm only looking to go 8'ohs in the eighth right now. I know some crate motor guys and one has a 350 Fastburn for sale rt now for $3k carb to pan. Went 5-6 tenths under. Plus I do some work for circle burner guys down here that run ZZ4's. I can get a good one for round $1500 then go through it. Anyhow maybe I'm dreaming but this looks do-able on the cheap. Dan this car will be easier cause I don't plan on street driving it so liberties can be taken in the name of et.

Re: Lil IHRA classification help please!! Newbie Alert!
 

Contact Mike Baker.

When racers show interest in a combination IHRA will make things work to better the sport.

Kenny:
My car has gone 12.88 on 14.05 and 8.15 on 9.10 index in great Cecil County Cold Air Day.
It needs to be heavy..4300 plus sized...Tar Heal and Corbitt know !!

AND still get 19mpg on the long road home...

Re: Lil IHRA classification help please!! Newbie Alert!
 

I sent him an email right after I posted.

I have this car that I would like to race, but would rather not put a cage in it as it is in pretty nice condition.

Re: Lil IHRA classification help please!! Newbie Alert!
 

Beautiful car! You don't need a bar IIRC until 11.50 so unless it falls into A or B/PS and you go really far under you won't have to deal with that. We should be right there in cold air but don't want to put one in either.

Re: Lil IHRA classification help please!! Newbie Alert!
 

WOW.. This is perfect for Pure Stock ...

Wagering it would fall into C, D or E/PS.
NHRA rated them from H/SA to M/SA

Re: Lil IHRA classification help please!! Newbie Alert!
 

Factory radio delete, manual windows, 37,000 one owner miles.

Re: Lil IHRA classification help please!! Newbie Alert!
 

It would almost have to be in a class (say turbo only).....to be a fair shake for the other classes.............I would not mind seeing it as long as they are competing with each other.....This is just my opinion and my opinion only........

Re: Lil IHRA classification help please!! Newbie Alert!
 

Fine with me.

Re: Lil IHRA classification help please!! Newbie Alert!
 

There must be a good reason for that.
I would love to hear what it is.


Besides the new V-6 Stangs, Camaros, and Challengers, I would love to see the new 1/2 ton trucks allowed in PS. (just dreaming out loud)
Alot of the 2011 and later 1/2 tons have strong 6 and 8 cylinder engines
My personal favorite is the 2011+ F-150 with the 5.0 Coyote, shortbed, reg. cab., 2wd.
I believe they run 14's from the factory.

Re: Lil IHRA classification help please!! Newbie Alert!
 

I am in total agreement. ^^^

I have a '87 Turbo Coupe I would love to run in PS. :)

Re: Lil IHRA classification help please!! Newbie Alert!
 

There are already 73 stock classes to choose from ,not counting automatic and stick classes together ........Killing me now with what we have...lol

Re: Lil IHRA classification help please!! Newbie Alert!
 

Yeah, pretty much they have. I have "most" of the pieces to put a SBC crate car together. Lack of time and motivation have kept me from pursuing it. I have a set of Parson's heads and the matching intake. Comp Cam and new Sherman lifters. Ross Pistons and a couple sets of good rods both stock and super stock. A legal carb that I got from Jeff Ross, built by a reputable person. The car already has a prepped rear with all Strange parts. Cal tracs and mono leafs. Have the pucks in the front subframe, need to rebuild the rest. Got the wheels and tires. Roll bar and frame connectors, just need to get them set up and welded in. Got a good 4 bolt main block with a steel crank, a donor from an old truck to build the engine from. They'll probably abolish the class before I finish the car.

Bruce told us we could expect to have $1600 or so in the block and crank work. I imagine with extras that figure will close to double. I gave him my modest expectations of what I expected the car to run. He laughed and said, if the car was set up at all, he didn't feel we'd have to worry about going that slow!

I love the PS concept. It's what Stock USED to be. My little FWD car won't fit into Pure Stock. Wish they pushed the same number of weight breaks as regular stock.

Re: Lil IHRA classification help please!! Newbie Alert!
 

The Turbo Buick in Pure Stock would be easy to Classify.

When they allowed SS like Cams in Stock.
That is when things became crazy.

What helps keeps PS sane is the Stock like Spring Pressures.
Before the SSizing of Stock you could put together a competitive ride.
Without adding a Roll Bar, or specialized fuel tank for super high test on low compression engine, Competition Seat belts that have to be recertified or bought new every two years.

There was no way to run SS in old Stock Classes.
In fact today's Stockers run SS ET's before the CHANGE.

For those that have restored classics. This is a perfect class to race them.
All you have to do is re-install the original cam, remove the stickers, polish it up, add the original stock wheels and tires.

Then sell your Numbers Ready Barrett Jackson special to the highest bidder.

Re: Lil IHRA classification help please!! Newbie Alert!
 

Aw,, whats wrong with a little road trip? In '03 four of us made the journey from Tacoma, Wa. to Whiteland Ind. to pick up my '68 Nova from the Shipp family,,, made it to Indy in 39 hours. Each driver drove a full tank of fuel and then we rotated. We grabbed a hotel the 2nd night and the 4th. We left on a Saturday morning and got back on Wednesday afternoon. Our boys, who had recently graduated from HS,, still talk about that trip 10 years ago,, it was about creating some memories,, and I still run the Nova.
The Camaro seems like a good deal,,, Texas to North Carolina,,, piece of cake!

Re: Lil IHRA classification help please!! Newbie Alert!
 

It's obvious some have not had the "Turbo" experience as some of us have. At one time I had a -1.20 under combo I felt could play anywhere. That's when I met Shaw's turbo Capri. Too this day remember reaching for the key in high gear thinking the motor shut off when he went by!!! I ran like -1.35 and lost by 10 car lengths! There's a reason for no turbos. I hope its true also about the rumors.
