Nitro racers predominantly use **5 camshaft bearings**, the standard configuration. The 7-bearing configuration is unique to Pro Stock engines due to factors such as their unique operating conditions and goals.

Maybe the valve train issues the nitro racers have are due to the cam issues

A Pro Stock engine has nine roller cam bearings. Also a much larger cam core.
Nitro engines would benefit from that update but there is a moratorium on Nitro engines and it would not be allowed.
