I started off on the wrong foot here. Rat Bastid helped me out a bit. I think usually the 408 will make more power overall but I tend to believe the 360 may make more per cube. My 367 made around 1.6hp/CI I believe I would see more power with that top end on a 408 but I think the heads would be a limiting factor and it may not make the 1.6 or higher mark due to rpm limitations. All just guessing with limited experience here though. Are we starting with heads set up for a 360" or 408"?
