I posted a similar thread on Fbody.com, I learned that even with a 427 stroker(was my question), you dont even need the 1 7/8, but until you've done the stroker and/or forced induction/big cam/head combo, you do not need the 1 7/8, i also have heard bad things about QTP lately, and better about kooks, one of the guys on fbody told me, that unless you're a real drag car, you do not need 1/8 over the outlet anyways, since the normal outlet is 1 3/4, you do not need 1 7/8 unless you are a drag car, also they claimed that doing the 1 7/8 on stock displacement will lose much performance as opposed to getting 1 3/4. Good luck, if i had a pontiac i'd do a 455 too but i have camaro, so yeah i'm stickin with camaro numbers(yenko w00t), anyways, yeah, go for it.

I agree...
