M1 Sb intake. Best for small blocks?

But they didn’t dyno the Performer.

there’s $100-$200 difference between hose two used. That money could be put for other HP gains or quality parts to grow with.
Oh I agree totally there's no way I would pay $100 more for an m1 over a performer, I was just pointing out that that's what can be expected from his for mentioned Cam and equivalent high-rise
