stock 5.0 block can only handle 500hp. if you are wanting 500 at the wheel you will be looking at 630 to 650 hp at the crank which is more than the block can handle. you will be able to do it but won't last for long. go with a dart block or mexican block. they handle more power.
and its true what bluebeastsrt said about breaking the block with less power. I split my block a year after doing a full bottom end rebuild. it wasn't correctly balanced by the machine shop, the balancer cracked in half which cause a HUGE mess. nothing was reuseable on that block. crank, cam, lifters, valve stems, heads, springs, rods, pistons, everything just either twisted or split. and that cuz it was just basic bolt ons. max hp i was making was about 250hp.
I attached some picture so you can see

Up til 92 the 5.0 had forged pistons. In 93 they switched to hypereutectic. Basically pistons with a high silicon content that reduces thermal expansion.

When people say the heads are no good they mean they dont flow any air! Aftermarket heads flow a ton more air than stock. A proper heads, cam intake swap along with a free flowing exhaust will put most 5.0 close to 11s. Slicks and suspension will get you there for sure.
