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

Those mods are nothing special, don't spend more money on the car because of them. "Internal work" to the heads is probably just ported stock heads, which are garbage. Stock heads are junk no matter how much work is done to them. The only things listed there that are worth anything in my opinion are the intake manifold, longtubes, and throttle body. If you are going to turbo the car... those longtubes are useless and the throttle body will probably be too small.

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.

Check AFR

Jesus, did it rip your oil pump in half??

It sure did. nothing off that block was reuseable. bought a 306 block and converted to carb instead.

It's cheaper because your dealing with a single head VS. 2 on the Mustang. Trick flow make good out of the box heads. So do edelbrock and AFR. It's the same principles with the V8 as it is with a 4 banger. (In your case 5 banger) Turbos dont like back pressure. So more exhaust is better. Just think about how all the 4 bangers run an open downpipe. You'll need to upgrade your fuel pump, Go to bigger injectors. (at least 39s) I'd go bigger. Tuning is a pain because anything before 95 is obd1. If you've modified turbo cars before just remember everything that applied to your old car applies to a Mustang. I took a stock SRT-4 from a 101 trap speed to a 120 trap speed with nothing more than a bigger turbo kit, intercooler and a little race gas.

why are the stock heads no good
i read a post were a guy ran 11's with all motor that is incredible black mustang coupe

does anybody know how he did it and wat all he did to motor

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.
