I don't know for sure, but I think the engine has a total of around 800 hours. It was freshly rebuilt when I installed the Whipple. So, it's 400 hours on the Whipple. It's 550 HP. I see you are in McHenry. The engine is in Ingleside, if you'd like to see it.

Yes, this is Everything! I replaced this motor with the Merc Racing 525 tweaked to 600HP. Just as a comparison, the Whipple motor pulled harder than the 525. But I did gain some speed with the 525.

It's a stock 502 Mag, stock heads, stock cam, JE pistons, and the already mentioned scorpion roller rockers. Because of the 400 hours I would want a refresh before going another season. I wouldn't feel comfortable sleeping at night without full disclosure.
