depends on what parts you have used, Ie, what mains, big ends, are the standard bearings, or Race bearings, or pinto bearings for that matter how much has the crank been ground, what bore is the block on, what gaskets seals, head gaskets, compression ratio, cams, turbo, we need a lot lot more info.
For all we know it could be a harvey 500/500 engine, or barry from round back has built it.
