Muscle Motors use them, I have a 4.5 stroke version, and a set of I beam rods..that look very nice, and measured well by me. I will know more in the next few weeks, when my machinist starts looking things over with his

I figure they are offshore cranks, and most come from the same foundry and finished at diff places. They need to be checked in every which way possible.
IMO
People complain about the offshore cranks, but once corrected they can live well beyond most people's power potential. I haven't be able to hurt one that's for sure. And I really have put the smack down on a Eagle crank and a 440 source crank (easy 850hp)

I guess if the crank mics out ok and the balance is correct it should live in an 800 hp combo.

We are running a 4.25 stroke RPM crank in the Duster this year. So far so good. Quality appeared to be as good as our 4.15 Eagle we were running.
