They are PEP, from the same manufacture as the 440 source cranks, just have a different name and p/n but are the same cranks.
 
I have one in our 400 stroker truck pulling engine that turns 8500rpm making 800HP, been in there for 3 seasons now. And I don't think its "On the edge" of what it can handle. These cranks are strong, they have the Big Mopar rod journal so there is a fair amount of overlap on the main and rod journals, that makes a crank strong.
 
Well if I get rid of the small block stuff it might be somthing to consider for the 3 440 motors I have in line to build. Not read much on BB stroker motors. Do you have a resource to look at?
