Anyone out there have a 4.0 ho stock camshaft from a 91-95 jeep they could take some measurements from? Or have already measured. Purchased a mild reground upgrade RV1 from delta and gave them my old one for a core already. Just picked up my machined block and head and had a little more shaved off than I had originally planed. Looking ahead for possible shorter pushrods. Just doing some pre planing for ordering parts for assembly.
Thanks, Greg.
