Thanks for the tips we'll throw it on "list by Craig" lol and see what happens. my cousin already has a Mallory HyFire ignition box (similar to MSD 6-AL), we're gonna use that with the stock electronic dizzy. We also bought a V8 k-frame it was cheaper than a conversion mount kit. I have heard a lot of good things about the GM HEI probably would have considered that if we didn't already have thHad good e Mallory box.
Deman360 supercharger actually sounds better than doing a full rebuild with Al heads etc. Throwing 10 lbs of boost up here would only be like 6 or 7 at sea level which is nothing.
