I actually got the motor from someone near me for $500..!! The head was redone and was done right, it is the part that the guy put together that went wrong.. He ordered connecting rod bolts, and the bearings!! That is where the problem came from, was the bearings. It either seized up or the torque spec was wrong..But believe me, i just put all that money into it, i thrashed it a little when i got it, then i stopped.:)
