Mopar 4.5" Crank

I've seen billets from Moldex, might want to give them a call. Also seen claims that KBRE(Keith Black) was supplying Mopar billet cranks. Not feeling comfortable about the reliability of that info, but it's possible.

Regardless, I'm not aware that there have been any crap manufacturer billet cranks, so you're probably good w/the Mopar part. Assuming it checks out for straightness, magnaflux and so forth. S/F....Ken M

Addendum: Even with good heads like B1's, a pump gas motor isn't going to exceed the strength of decent parts, assuming you don't try to push the "pump gas" thing too far. Detonation will kill even pro-mod level parts. If you're set on a certain power level, I'd run E85 on the street.
