300 6 rebuild
I am planning on rebuilding my 300. It is in a 77 p/u with a c4 and 3:07 dana 44 rear end.
Anyway I want to get another 100 hp out of it. What things would I need to do in order to do this and are there turnkey motors out there that sell such an animal? Do any of the sponsors have parts that I can use?
Any advice will be greatly appreciated.
