And so it was !

Thanks for that info ! I most likely would have never even looked at the S/G final.

Just a word about the winner of that race. My wife & I use to run against him, bracket racing at I-20 Dragway, in Tyler TX. They called his dad "Fast Eddie". So we called him "Little Eddie". IIRC, he was just a teenager, back then. I think he was driving a Mopar -- maybe a GTX. ? He was pretty good, even then. We couldn't beat him every time. Anyhow, he went on to make a big name for himself, in drag racing. Hey, that's just a little drag racing trivia for ya'll, from days gone by.

By the way, for those who don't know, the '68 Bird that Julie Biermann drove at Indy belongs to Tim. He also ran a real nice '68 GTO, a few years back.

A few things to think about if building a GT car. The first would be the cost of the core car and parts availability.. The cheapest would be the 79-81 Birds. Parts are readily available for 67-81 cars. 82 to 92 cars require more work to find parts and cost more but you can find aluminum hoods and front bumper bars.

Aerodynamics play a part in this. In GT you would be likely running up a against a jellybean car like a Cobalt or a Sunfire like Don Kennedy's during class eliminations. Sorry DK but your Sunfire doesn't have the cool factor that your last Firebird had. I have been told that the 91-92 Birds were the most aerodynamic cars Pontiac ever sold. 2nd gen Birds were GM's first computer designed car with at least thoughts about aero.

Body and engine fitment should be looked at. Pontiac had to redesign its air cleaner housings and intake manifolds because of the low hood line of the 2nd gen cars. Do you avoid a shaker hood or jack the carb on up in there? A Qjet and a Victor intake will fit under the hood of an 82-92 car. If you ever changed spark plugs on a 67-81 Pontiac, you would be amazed at how easy it is on a 82-92. In the 1980's people complained about the increased cost of chassis work on an 82-92 but now consider on a gen 2 car will you have to replace all the sheetmetal from the spring pockets back while moving in the framerails? I wouldn't even think about doing a 4th gen car even though I know some have been done. A more interesting choice would be a modern GTO with traditional Pontiac power. Good aero, was built with a Chevy v8 and donor cars are out there. Did you know if you put a 6x 400 with a manual trans in, the class designation is GT/O.

Now there's an Idea I hadn't thought of. Anybody seen or heard of a Pontiac powered GT car, using a late model GTO body ?

I like it !

No, and the wheelbase is quite long, by comparison.

From a quick Google search, looks like it's shorter than the earlier GTO's, but longer than Birds.

So, is that a bad thing ?

I mean, is it a "shorter is better" deal ?

Took a look at the GM GT cars on the Indy Q-list. Looks like most are Cobalts, Cavaliers, & 3rd gen F-bodies.

There were a couple of late GTO Stockers there. They were both running in the 10's, with 9" slicks. So, with a '77 Pontiac 350 engine, there shouldn't be any problem running in GT, with a Stocker suspension set-up .

Looked up some prices. There are some higher mileage cars for around $10k. This 1st one is the cleanest lookin one I've found that is well under $10k. It's $8,599 (OBO). So, there should be some decent race car candidates out there for $5k or less.

$7k

This one is $6490, with a bad auto trans.

How 'bout a '74 ? If you have to start from scratch, starting with one of these or a 2nd gen that came with a Pontiac engine might save a little work & money.

I have considered building a late model GTO with a Pontiac Power Plant for a few years. The issue is the independent rear end. To get one of these to handle alot of power it will take some serious $$$$. Prices I had quote to do the cage and convert to either a 12 bolt or 9" came in around $7500. So you would have around $25K in just the roller.

For you guys who won't race a GT car unless you can run more than a half sec under, you can quit reading this post now.

When I was racing, I never had enuff money to go as fast as I wanted to go, either in Stock or bracket. But, in bracket racing, we learned that you don't have to go quick, to win. You have cut consistently good lights & run consistent ET's.

Most Stock/SS racers really HATE it when you relate their chosen form of racing to bracket racing, in ANY way. BUT, IF your car is legal & can run it's index or a little quicker, then each round that is NOT a same-class heads-up race uses bracket race rules.

Since this IS true, no matter how many Class racers don't like it, any car that is legal & can run it's index can win any race, in which they don't have a heads-up run.

So, with this in mind, IF a guy really wants a GT car, but don't have the funds to build a high dollar car, he could run the '77 Pontiac 350 engine & get by with enuff car to run mid 11's.

That means that he would not need any more traction than a high 10 sec or low 11 sec Stocker would need. To me, that means that a decent low 11 sec Stock roller would be enuff car to run GT, with the 350P engine.

Or, if you had to, or wanted to, build from scratch, you wouldn't need any trick suspension. The basic leaf springs with Cal-Trac bars should work just fine. It appears to be working for Larry Maxwell, down into the 10.80's.

The '77 350, running in the lowest GT class, would require a min weight of 3500 + 170 driver weight. The '79 Bird is listed at just under 3500 with both a 403/auto & a 400/4-speed. So, one of these late 2nd gens should work great, as a GT/QA car, with an 11.75 index.

Brad Koivisto runs a half sec quicker than that easily, & has run some high tens, with his '74 350 GTO Stocker. IIRC, Mike Morgan has run below 10.50, with his '77 350 powered Bird

So, I'm thinkin that a real mild '77 SS 350 should easily run mid 11's, or slightly above, certainly quicker than 11.75.

Ya'll check my calculations. I could easily be wrong. How does this combo look for a low budget GT car ?

For those who don't think it would work, lets hear your recipe for a from-scratch low budget GT car.

Obviously, IF you can find a suitable & cheap roller that needs little, other than an engine & trans, then that might be cheaper, and a LOT less work, than building from scratch.
