Not Ranked
When prepped properly, a cast crank is good for 600 hp or so. Mine makes 585 hp @ 6,000 rpm. I beat the snot out of it and have never had a problem (and no, not with slippery radials, but with BFG drag radials that are very soft and hook up great). Sell the steel crank, buy a 428 crank, and the left over money will pay for the custom pistons that you will need for your stroker, which should be the only additional cost of building a stroker vs. a stocker.
Most engines spit rods out the side of the block when the rpm goes too high. You will never have that problem on a street stroker, mine never sees anything over 6,300. No reason to go any higher. It has bounced off the rev. limiter (7,000 rpm) a couple times on missed shifts (nobody is perfect) with no problems.
