Help me build a fast 440!

. I have to kindly disagree. The performer rpm intake is best for mildly upgraded 440. Its outta breathe at 6000rpm.

It had impressive performance in a somewhat more than "mild" 383 (263/[email protected] cam), but of course that's a significantly smaller displacement too.

I'll see how it does in my 451 once I get the 950 carb dialed in (and have enough nerve and straight empty road to wind 'er up) :eek:
Then it might be time to try an M1 or Victor intake (and possibly a 1050 Dominator)...
