Thanks

Not if they're made with crap steel..... You can get some good stuff out of China, but it takes a concerted effort at QAQC and most places are looking more at the cheap price. I wouldn't take a chance with them.

GM steel cranks have proven themselves at well over 1000 hp. Now a crank that has been machined down and depending on the abuse its sustained over time will be weaker than a new crank. I purchased a Ohio Crankshaft crank and rods for my 496 rated at around 1500 hp. My 8-71 Blown 496 will be around 1000 hp. I would suggest buying parts based on your hp output goals. I have a GM steel 454 4" stroke crank that is internally balanced and fresh turned .030/.030 It was in a stack injected 482 Rat 68 Chevelle drag car with 15 plus years of mid 9 sec passes. Started out std and turned down over time as needed. I would trust this crank in a mild street engine,...but not all out racing like it was used before.
