I Bought her in april i believe of 09 for $100 from the original owner with a old blown up 200-i6.luckily my buddy had a 76 stallion that he gave me and i pulled the tower mounts and the exhaust set up for the duals. has a 9 inch rear with a strong c4. after i got it all set up me and a friend built a 302 for it 0.30 over fresh heads mild cam edelbrock intake Accell Super coil and a Mallory Unilight Distributor. she's pretty snappy but i need a bit more. So i'm going a step bigger and putting a Boss 302 in it probably next winter and i'm gonna build the hell out of it.
Why would you put GT40 heads on a Boss 302? It would no longer be a Boss if you took the Boss (Cleveland) heads off!
