I'm new to the group, so forgive me if I'm posting this in the wrong spot. I have a 1966 Skylark with a 310 Wildcat (300) with a ST300 transmission. I'm considering a swap with a 455/TH400 combination. Can this be done? What problems will I have? Will it fit? Can I get headers that will fit by the frame? Any issues with the engine that I can address while I have it out?
