318 v 360

72, Regardless of the engine, the rest of the system needs to be turned a little more "perforamncy". That was my point. You could drop in a 400hp 360 and proceed to wipe the tranny and blow the rear up...lol. Or you cang et the car ready a little at a time, taking note of how each change helps the existing 318's performance, and then upgrade the engine to whatever you can afford. When I was a teenager there were many weekends I was riding in other cars because I could build power, but kept breaking things "downstream".
