I would call Dwayne and buy the cam through him also  I agree. Without a doubt, call Dwayne and let him spec a cam for you. He speced a cam for a 505 rb that’s in a hevy 4200 lb b body with power brakes and it runs 11.50’s at track, made 609 hp on dyno and is really very streetable. I couldn’t be happier with his cam!  Best thing you can do is call Dwayne.
