If you google "stock zz502 dyno results" you'll see that Car Craft did some testing and they made 516 hp and with a little tweaking got 528 hp. Lots of info on Mr. Google....

Went to a car show last year and they brought the dyno out. Pay $75 and you could get dynoed. Guy had 68 camaro with the 502 in it. They had a big srceen monitor set up so we could see numbers. He had exactly 503hp/600ft lb tq. Id say i was pretty convinced

502

That 503 is rear wheel horsepower too so with the powertrain loss that is a real good number.

If im not mistaken the only mods he had done was a cold air intake. It didnt have a real choppy idle but sounded mean. He stood around for a second as we looked at his car and I over heard him say cold air intake. Otherwise straight from GM
