**600hp sbm block limit? Or is it bs!!**

Well another "Myth" Busted that a 4" Cast Crank will break right away if you have over 500HP....... 1100 Passes, You got your $$ out of ANY ENGINE with that many runs!!. Well done! :cheers:

So which Cast Crank were you using??
Yeah, man!

I went with forged internals to take the abuse of nitrous, but if I wanted to build a budget stroker, I wouldn't be afraid of using a cast crank now. LOL!
