what has anyone done to their ls1 to improve the performance. like stock stroke vs a stroker crank {crankshaft,rods,pistons,camshafts} say if your going to get the car down to 3200lbs,turbo 400 no brake,4.56 gears for a efi true street heads up racing on 275/50/15 drag radials. knowing that i will need some n2o what kind of cam would you go with. intake system- victor jr. with a 105 accufab t.b.- a [stock] type intake, like fast,weiand,any other type aftermarket intake. will be installing this into a 96 firebird.

 

Depends on how many RPM's you want to spin to really.. that's where I would start anyways..

 

i would say around 6500-6800.

 

My 402 pulls that without a problem, I don't see why a 383 LS1 could do without a problem.

 

merv, what would you suggest on the induction side of this.
