Can you run a lightened crank with the hemi? The crank currently in mine had to have weight added to it. I have the eagle crank with manley rods and J and E pistons.

I am. I'm running a 440source lightweight crank with gun drilled mains and cut counterweights. Worked good for years although the thrust bearing on the last rebuild was marginal. Also, at Norwalk CC I started to lose oil pressure and had slowed down by almost a half a second. I think I might have trashed a thrust bearing. The bad part about it is 440source doesn't make a lightweight 4.15 stroke anymore so if it's toast I don't know what I'm going to do???

I haven't had the time/motivation to pull the pan. Oh, and it did balance at around a 2300 bob weight.
