Somewhere between 50 and 1050 hp will split the block. Depends on how well it is tuned, how low you keep the revs, how hard you drive it, and how much luck you have.

Once you reach the 500-600 hp level, all bets are off, but there is no magic number that instantly result in a block splitting. There have been plenty of racers pushing 800 hp out of a stock block and sometimes they last a whole season.

88 GT CHI headed 351w 10.8 @ 125 - still figuring it out.
03 Cobra 2.3 whipple 10.7 @ 129 - sold it
04 Mach 1 12.7 @ 109 mostly stock - sold it
89 LX procharged 302 515 hp 497 ftlbs 10.7 @130 mph - sold it

True, but if you sort of look at an average driver, well tuned car I would say 450 is a pretty safe bet. There are indeed a lot of variables, but I would say at 450 he shouldn't have too much to worry about.

you would have to change some internals to be up at that kind of power..

550-650 at the crank i think is about the limit, unless u have a early block, or mexican block.

its right around 500hp but like people have said variables are the killer..yes people have seen 800hp stock blockers, but i've seen slopyjosey's 300hp stock block split..i really myself wouldnt try it over 500hp..but an aftermarket block isnt a bad idea at any point, or for cheaper a 351w block..mexican blocks also have a higher nickel content so they technically are supposed to last longer but like i said..you could split it at 225hp...so all bets are off at any point

you could slap a 150hp shot at it a be safe, with a wet kit maybe 200..or like you said slap a nice little turbo on it, or s/c or even stroker, but i see it as if you tune it well and take good care of it, i dont see why not it could live a healthy life around 500hp..

wt im dreamin up is just goin down the the junk yard and finding a turbo diesel truck (there are tons of them around here in colorado) and just pullin off the turbo, and or finding a stock turbo off a ricer, like off an eagle talon, and putting it into my mustang with a good tune, find a small enough one that i might not even need a boost controller to regulate lbs of boost. sound fun?

If I'm not mistaken a steeper gear leaves you at a higher rev?
