Do you have billet splayed caps? 4340 crank? If so,my guess on paper would be around 500hp.Anybody else?   WIEDER

It more than likely can handle a little bit more than 500 horsepower but please realize that it's very difficult for us to determine...

As horsepower goes up tolerances need to go down, and eventually need to be eliminated. The more power you make the tougher it is for ALL the components to handle. We aren't building your engine so if one bearing is a little too tight and you think that the rods, pistons, and crank are STRONG enough to handle 575 horsepower but that much power at that kind of speed spins a bearing then we couldn't have predicted that for you...

It's also worth mentioning that dyno-proven horsepower is a lot different than estimated horsepower. Especially if you're a backyard builder and aren't going to dyno these engines and aren't going to push their limits in competition it's more likely that your buttom-end will be safe since there's a very good chance that your actual power may  be a little less.

Easily. As long as you use good bolts for the mains and rods. If you wanted to throw more boost at the motor, or just for extar insurance, I'd install a main girdle for some extra strength.
