Used Molnar 4.250 crank and Rods in a Hemi a couple of yrs ago. They measured as good or better than the Callies setup in my Small Block stroker. Spoke to Molnar himself on the phone before ordering and after he explained his Qualiity Control measures I was impressed. We probably talked for 45 minutes, where do you find that type of care for customers in todays World. The Hemi is a beast.
