LS2, stock heads, strong cam (Comp, Texas Speed maybe), tuned, no other mods. Are 1 7/8" primaries going to kill torque? I could see on a 400+ cu in motor, but is this too much for 364 cu in? Looking at Dynatech for great fitment and price. Like the stepped 1 3/4" to 1 7/8" but it's a huge jump in $$$. Input?
I'm thinking 475 flywheel HP is very doable. I'd like more but don't want to go crazy and risk PTV interference, plus drive ability is very important. 1st Gen F Body w/ T56 and 3.55 gears.
