built ls3 with stock crank i understand the stock cranks are pretty durable, but how do they like RPM? i l plan to turn this motor around 8000 RPM. can the stock crank handle this? and yes , the complete rotating assy. has been fully balanced. any input will be appreciated.
I know a lot of dirt circle track racers that use the CT525 crate engine (carbed LS3) With the stock crank and cracked rods they spin those anywhere from 6500 to 8000 depending on the gearing in the car. They seem to hold up just fine.
