Fwd chassis versus RWD Et
 
When it comes to advantages or disadvantages, how much does it appear using a FWD conversion is better than older RWD chassis. I have heard some report as much as .15 improvement when they place drive train in FWD from their older RWD cars.... Any input?

Kinda depends. As for GM cars, if you don't need to be under 2900/3000 lbs it would be hard to beat a '93/'02 Camaro/Firebird at that weight. 101" wheel base, with the engine set back. Half the engine is under the windshield & dash. Pete Peery told me that my driveshaft is like 8" shorter than his little GT car. You can run smaller tires with more air. When it gets hot, and my friends with the "jellybean" fwd GT cars start spinning & talking about the track going away, my car can't tell the difference. Likely not as easy a car to work on, however.
The reason you see so many running GT classes with carbs, ain't because they came from the factory with fuel injection. :-)

This is another one of those questions that depends on who you ask. Jimmy Boburka had a VERY nice, well beat to death F-Body Camaro. He built a really nice Cobalt and did exactly as you mentioned . Everything he could use he did. Motor, Trans, 3rd member, ...everything. Of course the headers had to be changed. He then headed to a track that he new like the back of his hand. He told us it was 7 to 8 faster.

But ,I've had one good friend swear that it is not nearly that much.. And they also have had both platforms.

Hard to think where it would come from, if we are talking about a 4th gen. Especially when the track goes away.

Gotta wonder where it is. A 3rd gen, I could understand.

Five if conditions are the same. A little more if there's any headwind. The front wheel drive cars are just more aero than the rear drive cars, Ed.

Learn something every day. Don't understand aero making that much difference in ET, no faster than we run, but I don't understand how bar codes work either. LOL

I know the one to get you a double shot for the price of a single, but I ain't telling...
