Yeah, that is why I said Roots, Whipple is much more M.P.F.I. friendly in it's desighn IMHO, I have nothing bad to say about mine. Also like I said above I don't think Whipple is a good option outside of Marine or Towing in the 1st place.Originally posted by: ScrapSilicon
vacuum secondary carb= no good but the Whipple design originally did do TBI 350 Chev trucks ..as for the Pontiac unless you girdle it and use h-beam type rods keep your rpms under 6500 as these engines were not engineered for high revs ..mostly for big cu inches for more grunt to get the land barges rolling(p.s. the Pontiac 455 is a small blockOriginally posted by: LAUST
If you want to keep useing your Vacuum carb you cannot use a Turbo or a Centrifical supercharger because you are pressurizing the carburetor, on a roots a vacuum carb works great because it sucks from the bottom just like a N/A engine.)
I have seen some "quick" Mustangs from Kenne Bell but none of them compete with the Procharged or Vortech cars I have seen.
Ooops, I was thinking the Buick 455
