Will these work on a ls5 72 chevelle?
Iam doing a ls swap on 1972 chevy blazer 4x4. Will these fit without hitting frame?
I have 2.5" between the block and steering u joint on my 5.3 ls. How far out will these manifolds stick out from the block? I need headers or manifolds that are as close to the block as possible. Any recommendations?
