quick question about a stock block

[mad max]

Is the stock block stamped with ford on it anywhere that you can see with a motor all together from intake to pan ? Have a friend trading a hayabusa for a mustang that supposedly has an aftermarket block and just trying to help him out in what to look for.

What block is it supposed to have? I have a Boss that I can compare pics of.

The only think I know is the VIN is stamped on the rear flat portion of the block where the lower intake mounts. Most of the time it has worn away, but some cars you can still see it.

The guy is second owner since motor was built. He can't remember brand name
And doesn't have any kind of receipt. The reasons motor has a vortex supercharger
On it supposedly makin 500+ hp.

Will this block hold together with a main girdle ? 500 rwhp is the limit or 500 at the crank for the block ?

Car has a stock block that was worked over by coast performance in california (main girdle, stroked to a 347). thanks for the help fellas.

There are a lot of factors; rpm, use, boost, and no certain answers. But, you are pushing the stock block's limits. It might last for years, but could split the next time you rip on it.
