THIS PAGE has 5 sites on it w/tip on 305's... Don't let anyone tell you you CAN'T build one to run. Anyone can have a 350, so why not run one of those so call "JUNK" Chevy V8's if you have one already. I put together a so-called "JUNK" 307 just because I wanted to & used tips from Fat Hack on HAMB...Joe
