Hello, I’m changing up my 408 a bit and need an intake manifold. Probably 6-8 years ago the “go to” was the rpm air gap. This is a street/strip car, it’s a 408 with 10.5-1 compression, auto 3800 stall and a 3.91-4.10 gear. Looking for opinions on the best all around intake manifold before I just jump on another air gap.
