Blew my engine this last race. Broke the crankshaft in half. It's a 440 factory steel crank in about a 650hp engine. Short block was about 9 years old and was at just under 600hp. Added new trickflow heads, dominator crb. And ported super victor and on the fifth run it blew at the top of 1st. My question is, will a factory crank live at 650hp and last or did I go to the well to many times.
