Questions about an intake for my 408 build A shop in chicago is building my ls 408. The intake is a holley 300-137 and I was wondering if it's a good intake and will produce good numbers. I see everyone else on here Running FAST intakes and that has me worried that my setup Won't be as good as others. The whole fuel injection system is holley too if that means anything.

It just depends on what you are doing. On a car with a 3500 or less converter and fairly low numerical ratio gears, the plastic factory style long runner intake manifolds will out perform the single plane intakes all day long. However, in a street strip car with a 4000+ RPM plus stall converter and a tall rear gear like 4.10 or better where the RPMs stay above 5500-6000 once you get rolling, the single plane will really deliver.

I really think a good ported Fast 102 is the best choice here, but that's just me. I mean I think the Holly intake will do good, I just don't think it's the absolute best choice based on your mods
