I'm putting Hedman Long tubes on my LT1 equipped 3rd gen. I'm going to run them into the hedman 2.5" extenders, then H pipe into high flow cats and finally dymax bullets and turn downs before the axel. Throwing in some BFG's for good luck. The tech told me to expect at least a 12% gain in power. Should make for a pretty wild ride, any ideas where the car could be as far as ET's go? My other mods are in my sig. I'll probably being doing the AC delete as well! Peace!

 

12% gain huh? no idea how he got that number. if you car needs more exhaust it'll pick up some MPH. no idea on ET, but i wish you luck.

 

With good traction you might be in the mid-13s range.

Stock converter?

 

Yeah, stock converter for now. I don't even know what stall to put in? I think it should be good for at least a mid 13 maybe even deep 13's. At least thats what I'm hoping for. Alot of LT1's have gone high 13's stock. With it in a lighter car, 4.10 gears, alot more power and slicks it has to bring the time down some. The car is quik right now, should really move soon!
