'94-'96 GM B-body 260/299 LT1 350 sedan or wagon stocker?
 

Anybody here race one?

Are they a viable combo without having to mortgage my home?

The sedans appear to be natural K cars, and the wagons appear to be natural N cars.

The best off the shelf headers I can find so far, is Hooker's funky #2063 ceramic-coated Super Comp 1-3/4"x3" headers, which appear to sweep up and over.

Is there any advantage to keeping the 4L60E, for it's 3.06 first gear? I don't think a metric 200 would be in the budget for me. It looks like there are proper 8" converters available for them.

Does Global West make Del-Alum front control arm bushings for them?

Who makes lightweight front brake kits for them?

I found single and double adjustable front shocks from Strange, but nothing for the rear.

I'd sure be interested in hearing from anyone that has raced one.

Re: '94-'96 GM B-body 260/299 LT1 350 sedan or wagon stocker
 

A VERY good combo but IMHO not cheap.

Re: '94-'96 GM B-body 260/299 LT1 350 sedan or wagon stocker
 

Thank you, Billy.

Please elaborate. What makes it good?

What would be involved in getting one to comfortably run under, without breaking the bank?

Re: '94-'96 GM B-body 260/299 LT1 350 sedan or wagon stocker
 

The biggest thing that "makes it good" is the HP factor. Compare it to an LT-1 Camaro, there's almost 60 HP difference for a slightly different intake and an arguable better iron head.

I don't know what you would consider "breaking the bank". You SHOULD get an aftermarket ECU, a GOOD 3-speed trans and you're going to have to fill up the 8.5 rear with GOOD parts or get a 12 bolt. The only place where I could see you "cheaping out" would be with the motor. I don't see the need for a bunch of trick parts to "comfortably run under" the index but you are going to need a competent shop that understands LT-1s.

Re: '94-'96 GM B-body 260/299 LT1 350 sedan or wagon stocker
 

Thank you. I noticed the 59 horsepower while going through the classification guides.

Re: '94-'96 GM B-body 260/299 LT1 350 sedan or wagon stocker
 

PM Corbitt Marshburn on this site . He has built the LT-1 powered wagon and could guide you down the right path.

Re: '94-'96 GM B-body 260/299 LT1 350 sedan or wagon stocker
 

Thanks.

I just PM'd him. He's been a member here since 2004, but he's never made a single post, so I wouldn't know if he even checks in here anymore.

I Googled his name, and found a pic of the black wagon. Is it a class car, or a bracket car?

Re: '94-'96 GM B-body 260/299 LT1 350 sedan or wagon stocker
 

Ditch 4/60LE transmission,will kill you
. Don't even think about it!

Re: '94-'96 GM B-body 260/299 LT1 350 sedan or wagon stocker
 

This is a great combination. Years ago, I worked with GM to get the wagon added. I ended up building another Firebird after Veronica turned her nose up at the idea of me racing a wagon. I still point out every one we pass to her!!

It shouldn't be crazy expensive to build a competitive car. It all depends on what your budget is and how much you can do yourself.

Re: '94-'96 GM B-body 260/299 LT1 350 sedan or wagon stocker
 

Billy is right,the engine is where you can save. I've built combos I just wanted to see if they were viable using cast pistons,home brewed low drag ring package etc. that weren't much slower than first class stuff. Good basics and preparation does a lot,might not want to run it forever but good maintenance and common sense driving go a long way. Sorry for the long winded response. Good Luck.

Re: '94-'96 GM B-body 260/299 LT1 350 sedan or wagon stocker
 

Thanks, guys.

I do like wagons...

Re: '94-'96 GM B-body 260/299 LT1 350 sedan or wagon stocker
 

I haven't seen a LT1 wagon racing for a while but that is what I would want to build I think that would be a reasonable build and fun to race. I raced 3 wagons through the 70"s and early 80"s loved them.

This a rocket combination. I set out to build it multiple times and still have a ton of core parts for one. This a 1.50 under ride in the right hands. I will tell you the stock rear end will expire quickly. The combination really needs a good 12 bolt. It is not a cheap ride but has great potential to be a number one qualifier and reliable.

Re: '94-'96 GM B-body 260/299 LT1 350 sedan or wagon stocker
 

KBB says they're worth about two grand, but the ones I've seen for sale all have pie in the sky asking prices four to five times that...

Re: '94-'96 GM B-body 260/299 LT1 350 sedan or wagon stocker
 

Thank you, Paul...

Re: '94-'96 GM B-body 260/299 LT1 350 sedan or wagon stocker
 

Also available in the Buick Roadmaster line.The wagon is in the guide..Don't know why the sedan is not.
Cadillac Sedan DeVille... Not in the book either, but I always thought it would make a good cruiser and street bracket car.

Re: '94-'96 GM B-body 260/299 LT1 350 sedan or wagon stocker
 

Yeah, I was looking at the Roadmaster Estate wagon too...

Re: '94-'96 GM B-body 260/299 LT1 350 sedan or wagon stocker
 

I belong to a large B-body club.

Own a 94 Caprice Wagon and 1995 Impala SS
Ran the Impala SS as F/PS at IHRA and Association races.
Best run was at Cecil 12.47 at 107mph at 4200 lbs.
Ran wagon when SS was down and ran 14.95 90mph

Wagon has a Boxed frame making it very strong.
Will fall in M or N/SA. Around 4300lbs in M.

Both cars use PerformaBuilt 4L60E’s.
Installed in SS 6 years ago and run about 20 meets a year.
The 8.5 inch rear is very strong. Lots of upgrades available.
Never broke a rear in the 95SS racing it for 20+ years.
Owned ‘since new.

Use a Truck case as it is stronger.
Have that one in the Wagon. installed 5 years ago.
Handles trailering the SS over the Appalachians in the heat.
Going strong..compared to the last 7 that failed built by others.

Just installed a Bullet Stocker cam moving to K/SA.
SS is Natural L. K Light and M heavy.
Decal the front grill with CAPRICE and run J/SA.

The chassis is the same as a 1964 Chevelle/GTO/GM.
Dick Miller has what you need.
The axles are slightly wider.
Use a Metco Lower Arm add an SS roll bar and Airbags

I have rebuilt every moving component in the wagon.
Been an ongoing restoration and has 270k miles and burn no oil.

Pulled the SS engine it had 205k miles on it.
Still had the factory hone marks on it.
Rebuilt as forged 383 and have not installed yet in the wagon.
Jeff Warren built the Stocker engine..

The Cylinder heads use the Vortex ports.
Joe Mondello wrote a article about it in 2011.

Prices are rising quickly as more get fixed up.
Hard to find one clean or with low miles.

Hope this helps.

14.95 is WAY off the index(es).

The others are telling me to dump the 4L60E.

What do you mean by a "Truck case"? Are you talking about the differential case? I'd be running a spool.

It's been about 25 years since I was underneath one of these things- they use the same triangulated 4-link that GM used in all their other mid and full sized cars for 30 years or so, right?

I think the stock rules allow relocating one of the mounting points on those to move the instant center of the rear suspension to improve the geometry.

You use an OEM SS rear sway bar and TWO airbags? I thought I remember people only using one air bag back then. Are there better rear sway bars available so that I can get away without having to run any airbags? I can tune a sway bar like that with washers.

What about headers? I See that Hooker makes ceramic-coated headers with 1-3/4" primaries that sweep up and over, into a 3" collector.

In any case, thanks for your input.

Re: '94-'96 GM B-body 260/299 LT1 350 sedan or wagon stocker
 

...and I would be interested in hearing more about your Bullet cam...

Re: '94-'96 GM B-body 260/299 LT1 350 sedan or wagon stocker
 

What wheel offset do I need to properly fit a 15x10 with a 9x30 radial in the rear? I'm looking at some of the black versions of the RC Components "Fusion" wheels...

Re: '94-'96 GM B-body 260/299 LT1 350 sedan or wagon stocker
 

The Caprice Sedan can run J.
The SS can only make K.
The wagon is a natural N car..can go M.

As for my wagon. It is set up for towing the SS.
FI grins bracket raced it ina hot day and Rand 14.95 that evening.
All stock engine with 3.73 for towing.

The Tahoe and truck came with thicker 4L60E cases.
Also a 6 quart oil pan. Which I have on my SS.

Mine has a Yank 4400PT Locking converter.
Mine is still licensed and can take for a car wash.

Have a choice to Lock up or use OD without screaming the engine.
However limited to 4700rpm stall on a 10 inch converter.
8 inch can go where you want with 5% top end slip.
Just turn off the Files to prevent Lock up feature up.
Using TunerCat and ODB1 tuning.

When you go under the car to see the chassis.
It will be familiar and 96 was last use of that chassis series.
It was introduced in 1964 for the Intermediates.
Then late 70’s 90’s Impalas. Rebodied 91 to 96’s

As for airbags.
You can get away with one on the right side.
Having good luck with both and can adjust the hit.

For cams big choices. Talk to Bullet cams.
NHRA standardized on the F-Body cam specs.
Do not know why.
If we had to use the B-body cam would put us N or below.

Re: '94-'96 GM B-body 260/299 LT1 350 sedan or wagon stocker
 

The SS and Caprice came with 2 axle lengths.
SS are a few mm longer.
No problem fitting 30x9 slicks.
I have rare Centerlines wheels with 3.5 backspacing.
Wagons have even longer axle.

I do have a complete 8.5 rear for sale.
4.56, Moser axles, ARP studs, mini spool.
disk brake to disk brake.
Have a PowerTrak in box.

Re: '94-'96 GM B-body 260/299 LT1 350 sedan or wagon stocker
 

My bad- I was reading the wrong line when I scrolled right to see the pounds per horsepower.

It is in fact 14.87 pounds per horsepower for the '94-'96 Chevy and Buick LT1 B-wagons, making them natural N cars, which would save me the expense of a roll bar and 2-year driver's harness.

I'm gonna go back and edit my previous posts, to eliminate the incorrect information.

Re: '94-'96 GM B-body 260/299 LT1 350 sedan or wagon stocker
 

Okay, so the N/SA index is 13.00, and the record is currently 11.99 @108 or so. Sounds like I'm looking at about a 5.57 rear gear for starters...

Re: '94-'96 GM B-body 260/299 LT1 350 sedan or wagon stocker
 

I really doubt it would want that much. Maybe 5.13.

Re: '94-'96 GM B-body 260/299 LT1 350 sedan or wagon stocker
 

Billy Nees. I have one of these wagons in stock.
Hmmm. Winter project?

Re: '94-'96 GM B-body 260/299 LT1 350 sedan or wagon stocker
 

Az Classic car site on facebook has a 92 Chevy Wagon, running driving with lt1 for 2800. Car looks pretty good.

Re: '94-'96 GM B-body 260/299 LT1 350 sedan or wagon stocker
 

Put 5.13’s in my SS.
Running 28inch tire, locking converter at 98mph.
If I go with a 8inch converter will go to a 30 inch tire.
Turn off the lock up.

N/SA you will be close to 4500lbs.

Re: '94-'96 GM B-body 260/299 LT1 350 sedan or wagon stocker
 

Sounds like you're doing your homework..That's good.
Just be careful who you listen to..This won't be a pure stocker.
OD trans planetaries and clutches and LU converters have no business in a good K/SA car. You'll leave too much ET on the table.
I think you already know that. ;-)

Re: '94-'96 GM B-body 260/299 LT1 350 sedan or wagon stocker
 

The LT1 wasn't introduced until 1994.

A lot of booger-eating crystal meth tweakers advertise their TBI 305 or 350 '91-'93 B-body GM cars as being "LT1" equipped.

They are among the same demographic that tends to refer to aftermarket wheels using the words "custom" and "rims"...

Re: '94-'96 GM B-body 260/299 LT1 350 sedan or wagon stocker
 

Copy that...

Re: '94-'96 GM B-body 260/299 LT1 350 sedan or wagon stocker
 

only one problem with this combo .... no stick ;)

Re: '94-'96 GM B-body 260/299 LT1 350 sedan or wagon stocker
 

You do if you want a reliable trouble free trans in a heavy car that will Last.
Btw last year my F/Pure Stocker was 18th under the Index on the list at Numidia.

Bet you you have something to say..!
Here it comes !

Re: '94-'96 GM B-body 260/299 LT1 350 sedan or wagon stocker
 

I believe he's trying to go fast not.18 under
Listen to Mark and get with the program. A good th-350 or 200 will be 4-5 tenths faster. It's not just about first gear ratio. You can make up for the ratio with the correct converter.

Re: '94-'96 GM B-body 260/299 LT1 350 sedan or wagon stocker
 

Yeah, I'm not trying to set a national record, but I would not be stoked with .18 under.

Re: '94-'96 GM B-body 260/299 LT1 350 sedan or wagon stocker
 

Did you guys happen to see Jason Line mention his 200 trans?

No further comment here...

Re: '94-'96 GM B-body 260/299 LT1 350 sedan or wagon stocker
 

I took it as number 18 on the list, not .18 under his index.
