yea it will hold a crap ton. no need to bother going forged unless your pushing over 1000+ hp

Im doing 600+ on 15psi. turned it up at the track to 17psi spiking 19-20psi. I still have the stock CAST crank in mine. As long as it isn't being grunted and dogged at the track and pushed hard...you will be fine. ON the street, that HP level a cast crank would work. Im proof...

I don't.
![]() Just that the street is easier on parts cause it isn't dead hooking and lugging the motor down low. There is much less stress on parts in the upper RPM range than off the line digging and hooking... |
