Beware: Plum Floored Creations....

On that motor I would call the cc compay and explain what happened. And the condition of the "low milage undamaged engine" and see if they will return your funds if you ship the motor back. You want nothing to do with it. I'm sure it will not last more than 20 min of run time. If you get that out of it. Btw I can get truck 5.7's all day long if you wanna go that way
