When I spec'd my cam,called several cam grinders to gather info for what I wanted to do.Funny how I talked to one cam Co. several times and recieved several different opinions.
So do your homework then speak to DP.He has alot of fast & happy customers

I have ordered several custom cams from Dwayne Porter and he also gets my recommendation. My last solid was nitrided and used the edm lifters which I think are cheap insurance. Give him a call!
