IHRA Pure Stockers?
 
Just curious, how many guys here run IHRA Pure Stock? What do you like/dislike about the class? What are you running?

I'm working on a Stocker (sssllloooooowwwwww) stocker, but reading through the rulebook this class caught my attention. Maybe someday?

Ran one for a few years.You do not get to run a electric water pump,so cooling down between rounds takes longer.Stock duration cam,and stock spring pressure must be used.

I like my pure stocker, cooling is'nt big deal I have 2 13'' electric fans on 26'' radiator hardly ever gets above 165.
Also have to have mufflers w/headers,can use elec. fuel pump but have to keep mechanical pump mufflers can't be straight through type have to be baffled.

I just bought an E/PS 83 Camaro. I've only had it out once. It's a fairly inexpensive way to go stock racing. Can't wait for 2013.

I'm running a 1995 Mustang GT 5.0 automatic in I/PS.

Bought the car off a car lot and changed the rear gears to 4.56, installed an off-road x-pipe, and put a shift kit in the AODE. Car still has the stock torque convertor (of unknown mileage) and power brakes, stereo, etc.
I came real close to the 9.45 index at the London IHRA Pro AM event last month with a 9.47. Two weeks later without any changes it ran a 9.328 at Beech bend.

It is basically a street car running in Stock with DOT tires and pump gas.
With mufflers and DOT tires, I can run that car in trophy classes at various tracks as well. Makes it fun to play with.

PS rules say you can run any size DOT tire (as long as it fits the stock wheel well)
No turbocharged or blower cars allowed in PS.
Driveshaft loop required in all classes.

I agree.
I paid $ 3,500 for my car from a car lot and have about $ 4,500 total invested in it. I feel confident a $ 350.00 torque convertor would easily get me .3 under the index.
I also am looking forward to next year.

I ran my 455/325hp 1971 Lemans Wagon in J/PSA . Lots of fun, got down to 3 cars at the Northern Nationals when they were at Milan, which is my home track .

The J/PSA class dosent exist ! I/PS is the lowest class at 16 lbs per HP. Pure Stockers are 1 lb breaks starting with 8 down thru 16 pounds per HP. Stick and automatic trans run together heads up. Page 54 of the 2012 IHRA rule book. Nothing has changed since I wrote the rules back in the "Stone Age" .

Sorry to pre-date your rule book, but back when I ran pure stock there were pure stock classes that mirrored all the regular stock classes, plus I believe there was a Double A and a Double B pure stock which one of my friends ran and set the record in Double B, with his 427/425hp , 69 Camaro . This was back around 1981 or 82 .

Re: IHRA Pure Stockers?
 
i have been giving this class some thought as a good use for the stock 68 Camaro sitting in my garage. What class would a 68 camaro 327/275hp go into in pure stock ???

Joe Toller 10-04-2012 10:48 PM
Re: IHRA Pure Stockers?
 
Sounds like a better deal than a slow stocker. I bought a 70 Firebird, 400/2bbl at a farm auction for $500, maybe I should scrap the V/SA car and do this instead!

I shouldn't have bought the car, as I had one to build, but no way was the scrap dealer getting it!

WOW.....30 + years ago. You didnt mention when YOU RACED THE WAGON. I guess you stay on top of things....LOL. Back then the cam had to be OEM, everything stock STOCK STOCK AND OEM street tires as when NHRA dropped the ball in 1972 and eliminated Jr. stock.

When I lived in NC I ran a '95 Impala SS in Pure Stock. Pretty good combination and not something you see every day. Nice way to have a street/strip "bolt-on" car that can run class without sinking the monstrous amount of $$$ some of these guys put into their cars.

Bought an '04 Corvette coupe last spring that I want to begin running in C/PS next spring. Bone stock (with our luggage in the back) it ran 13.3 at Ennis this summer at Super Chevy. Index is 12.75. Horsepower and AFHS is very favorable for the LS1 in a C5 as opposed to the Camaro/Firebird. I've since added a nice cold air kit, Z06 cat back, and tune. Should be in the high 12s or right at 13.0. I'm thinking a gear change and TC this winter will put it solidly under the index and I'll still drive to the track with the AC on. Heck, there is a guy in Florida that drives his to the track and easily runs under the D/SA index in NHRA.

Should be no problem. I have several stock LS1 F body customers running under your index, with heavier cars. A couple with stock gears & converters.

Reading www.corvetteforum.com they have an ET list and there are many, many under the index with only bolt-ons and a ton more than a second under. I think the quickest one is in the low 11s which is more than 1.5 under. I'm thinking about going with a 4.10 gear and Yank SS or PT4000 since it's not a daily driver.

There was a little clue in that thread about how long ago I ran pure stock. Milan hasn't had the Northern Nationals for quite awhile. Milan went NHRA soon after, and lost the Northern Nationals title, when they went back to IHRA, they got the Motor City Nationals. Now they are back with NHRA. I guess that is what happens when you race at the same place for 35 years !

Re: IHRA Pure Stockers?
 
I have a 95 Impala SS, a car like TarHeel, and Corbitt Marshburn. It is driven to all the races and the trunk is huge and can take everything needed to the track.

Gas Mileage is at 19mpg. Been racing it since buying it new in ECIRS as a Bolt on and over time got it running well under the IHRA index.

Since then the car has a new interior, paint, complete new rear, Warren engine, Shane tranny, Yank converter and has run .85 under. Few more mods should go a full second.

But would have to take it off the street to do that. Such as more gearing and tire.

For now on a hot day will still run a half second under and have the benefit of AC driving back to the pits..:-)

Re: IHRA Pure Stockers?
 
Any advice for someone looking at this class? The car in question is a 70 Firebird, 400/2bbl (265hp), puts it at 13.00 in the books and a F/PS.

Any suggestions on the 2bbl? The combo in general?

Hemiparts 10-08-2012 10:42 PM
Re: IHRA Pure Stockers?
 
i'm also very curious about this class for next year. What class would a 68 camaro 327/275 auto fall into ?? and where would you find the spec's for the factory 327/275hp cam?? what trans would i need to run PG or turbo 350 ? Looking forward to trying to put something together for next year.

Chris

Re: IHRA Pure Stockers?
 
IHRA will have the specs for the older combos,I would say anything 86 or older they will have cam specs because they used NHRA specs and NHRA specs had duration,overlap,
and spring specs till 86 at least.

IRACEITALL,
If I could have 4bbl combo I would try to do that,2bbl is harder to make work and weather will affect more.

Hemi Parts
If car was 2 speed then you will have to use glide if was three speed then can be 3 spd just remember can't have manual valve body.
Sticks and autos run together might as well go stick and have fun
I would try call IHRA office and see who can answer your questions used to be Mike Baker, Hank Blakenship could tell you(he's does'nt work@ office) or I say Terry Bell still remembers

NIX on the 2bbl, run the QJet 4bbl version.
Lot more tuning parts available.
A popular Car and similar period car Pontiac racers can sell you one already set up.

You most likely be running D/PS instead and having more fun.

Any tricks or go-to guys for the TH400? I dont find where I could use a TH350...

Mike Taylor 3601 10-17-2012 09:42 PM
Re: IHRA Pure Stockers?
 
I would check and see I think as long as oem type trans and no manual valve body and 3 spd.

Automatic shifting T350 with 400 would be a good combo.
