cam recommendation

It’s not the compression ratio you have to worry about. Any cam will work and well. The heads ability to flow air, or not, is more the issue.

Reason being is that the NASCAR Truck series (when new) participants were asked about there engines and there limited to a 9.0-1 ratio being a problem there response was, “No problem! While more would be better, we worked around it.” And that hp tune was over 700hp on a 9.0-1 ratio.

Choose your cams duration based on what rpm range you want to make power in and get as much lift in on as you can to take advantage of the heads flowing ability’s. Equipped it with the proper stall and etc....

Have fun!
