Have 650 hours on mine. Live in se Michigan. Anybody reccomennd someone to rebuild??

Call Eddie Young he has package for these engines. They make 600Hp and still behave like stock. He did the three of mine. Peak torque is at 3900 RPM peak horsepower is at 5200.

got a contact #?

That is a lot of hrs, did you have any top end work done to get you to the 650 hrs?

They did at three hundred hours.

I very strongly recommend Frank at Scorpion Racing Engines in Livonia. He has always treated me right, far better than any other engine builder I have known. Let him know I referred you. 734-306-4147

Eddie Young's # is 615-216-7449. He gives great customer service. Check the threads on here, very positive feed back.

Thanks for the information.
