I have a ford 9in rear that’s 3.5:1 and I want a na 318 in just looking for a good performance motor from a roll I would like to keep the stock converter and the 904 trans I have I can add a shift kit if necessary I just didn’t do that when I built it the first time. I’m just looking for a good reliable performance motor. Nothing crazy I would like to use my 4 barrel intake and a 750
CFM carb obviously I can rejet it if necessary. I want the 318 but I don’t have to have 318 heads I want to keep the rotating assembly but will change piston heads. If that puts it in perspective.
