Jeff is correct...My 64 started out like your car. My iron head 446" was in the mid 12.xxs. I had a 3.91 rear and was at the same weight. My intake was an m-1 with a Bigs 950. I also had a solid lifter cam in it. The converter was a PTC 4200. Got some weight off the car and put aluminum heads on and it eventually came down to 11.50s. If you shop around there are some good deals on here as some guys are stepping it up a bit. Good luck and keep us posted!! Ted
