I had a truetest engine put in mine when the engine went. Ordered in the afternoon, it was delivered to my shop the next morning (KY to PA I think). Decent cost and the shop who put it in was impressed. They only installed Jasper before, and thought about switching after the good service from truetest and quality of motor. 3 yr/ unlimited mileage warranty if I remember correctly. 4 years later for me and no complaints.
