I plan on buying the LT4 HOT cam along with some heads and an intake manifold for my 355. I already bought SLP runners and I will be porting my plenum and buying a 58 mm throttle body. I want to run in the 12s. I have the suspension stuff (adj. torque arm, lower control arms, LCA relocation brackets, sub frame connectors, 3.42 gears, slicks). Now I just need the motor stuff. Thanks.

 

You could use a vortec combo with that cam and probably see low 13's


Otherwise AFRs and super ram
