I purchased a complete 5.0 coyote motor out of an 11 GT that has a bottom end knock. The motor is complete from intake to oil pan, factory headers, injectors, engine harness, flywheel and clutch with 70K on it. The guy that I bought it from put a Vortech on the car and started driving it around without a tune, and that's how it developed a bottom end knock. I originally bought the motor to have a race short block built for my 12 Gt that I was drag racing, but I have since traded that car and some money for a 11 GT500. I considered selling the motor but don't really know how much to ask or if I even want to sell it, I would love to put it in an early model Mustang.
