Actually never saw the picture of the Hot rod crank, when I email them, if they are any better, they stated is just built to OEM specifications. I know they sell them sometime on E Bay, but funny was seller used Crankworks billet crank for picture. But honestly pinned stock ones hold pretty good. IMHO
I try 13 PSI without problem, but go back to 11, because I really don;t have idea how high is a safe limit of the boost on pump gas to protect pistons.
