If he was really an undercover cop he wouldn't tell you. Have it inspected by a speed-shop..not an ordinary mechanic. Have it put on a dyno to see. It may cost you a bit but will give you real answers.


Even a 427 M-6007-Z427AFT $16,000 engine puts out 570HP. The Roush blowers are all well and good but 650? I think not ...what is embossed on the valve covers? Cobra? Ford racing? Anything like that?

Well it's an original gt with the supercharger put on afterwards. It looks legit I just don't trust the guy

Trust your instincts. Something intangible is telling you not to trust him. He already lied to you once...like I say 'undercover' means just that, not "hey, I'm an undercover cop so I need...." Baloney. Your gut feeling is right. That being said, I'm NOT saying don't buy it. If you like it/want it/have the money, more power to ya (No pun intended) but 650HP....I wish I could see it. Possible, but.....

I agree with fordnut. Follow your gut. Better to miss out on a good deal than to have to say "knew I should not have bought this from him"

dandy is right, For agreeing with me. Just kidding...but seriously, he is right. There are plenty of Muscle Cars, Mustangs, if that is what you are wanting or just ran across this guy. You can get a 400HP HO 5.0, one of the best engines Ford ever produced IMO that will burn rubber until the tires are gone, in a cloud of smoke that Kevin Harvick would envy. That car came stock with a 4.6L 300HP, and rear wheel drive, something getting more difficult to find, but that GT has it. Then even with the blower and positive pressure induction, sure will add a lot of HP but not more than double. Not even close

Well I've been looking at one that seems more legit 2006 gt with kenne bell supercharger and he's saying 479 hp and he has a safety pulley on it he says it will push 550 with bigger pulley which is correct according to kenne belles website

That's backwards. True, different diameter pulleys change boost. But a smaller diameter pulley spins faster, increasing induction psi

Yeah I just said it backwards haha
