Alright ,I have a mild :lol: 496 that I built for another car. That car is on hold right now, so I am thinking about putting it in the 79 Bu. The Malibu does have A/C and I don't really want to rip it all out. I guess I would like to know what you guys are running (motor mounts, headers, etc) for a BBC swap. I have found some old threads that have pics of Malibu's that are running A/C and tall valve covers. What are the secrets to the swap? Any information would be great.
