440 cam help

A few things...

insert eye roll....

There is nothing wrong with comp cams. read that again. Some of the best engine builders in the world use CC.

Advertised power ranges means very little and mostly nothing. read that again. There are so many variables that affect this they might as well not even list it.

you need a cam that builds cylinder pressure. So you can either read up on that (start with a tighter LSA) or you can call and have a custom cam cut.
