COMP Cams Nostalgia Plus

IMO, just IMO, I would use the 3.55’s or numerically higher gears. I myself would not use 3.23’s. Also, a 3K stall would be fine IMO.
Have you considered the use of 1.6 rockers. It’ll be a .505 lift then. Your really not using the available port flow which is really good.

.474 is bowl porting territory.
