I agree with the one above post..Start off with a 400 block and build a 500hp screamer with a much lighter rotating assembly..I have a 1974 400 block that has already been checked if interested..

1972 Road Runner / GTX 440 4spd Dana 3.54 Just about to turn 26K original miles..

A boat, a GMC truck, some Craftsman Tools, LOTS of Zombie Protection, and a few Goldfish..

If you love someone set them free..
If they come back it means nobody else wanted them either..!!
