Best Intake for a 408

12many said

So what best all around intake does the OP need with what he has? (not what he should have or needs to change in order to run a specific intake) He’s mentioned possibly using a cam with 260° @.050” and higher lift:

A) an OOTB Air Gap
B) an OOTB Victor 340
C) a ported Victor 340
D) Other OTTB Single (SV/Indy etc)
E) a ported Other Single

From what I’m reading here it’s between an OOTB AG and a ported Victor 340.

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



I never played with an air gap but isn’t it a copy of an LD340? I jumped back to the beginning to see what heads he had on it and what he would like to accomplish which I didn’t find but with a gasket matched Air Gap it’s easily in the 11’s with what he has right??? If he’s happy in the 11’s just match things up and have fun. If he wants 10’s then changes are needed with the converter and probably heads. 11’s are damn fast and fun for lots of guys.
