The best thing to do is make it your way, make it your car. There is no replacement for displacement. They also have much better cam designs now for drivability and power. Even where they make good vacuum for power brakes. Best thing is to contact a couple different cam company's and they usually have a couple different cams where they will fit what you want. You will need to provide some info like rear gear, trans, compression you are using, heads, but doing all that will really pay off.
