Also, I had 525 to the wheels with my vortech for about a year. Never really beat on the car too much though because I feared for inevitable. When I bought my Dart setup, I stripped the stock block down and gave it away to a coworker of mine that restores classic mustangs. He did an ultrasound test on the block and found all kinds of stress fractures. It was basically a paperweight after that. Time and RPM certainly kills those stock blocks. Not if, but when.

the steel crank is stiffer than cast and will actually help a stock block stay together because cap chatter is a big contributor to cracking. the steel crank wont prevent the block from cracking. but for a given application it will noticeably cut down on the little caps dancing.
