Smallblock intake manifold shootout.

I,m building a 408 stroker with the Eddy RPM heads.I wanted to see which intake flowed better with the Eddy heads.So we tried the Air-gap,not bad.Then tried an old single plane Pro/Street intake I had laying around that I bought really,really cheap!The old intake outflowed the Air-gap by an impressive margine.Not sure if the 3,s are cc,s?,but it was 63 airgap,69 with the Pro/Street.I,m using the old one!:toothy10:
