Do not go with power transmissions. look them up on the internet. They used to be mid atlantic. check that out too. Jasper is a little pricy, but they have a great warrenty. Also check out Ford, they are usually in the ball park for money, and warrenty. I rebuild my own, you can get the parts from P.A.W, and take the block/ heads etc to a machine shop like doug's welding. why do you need a complete rebuild? What are the symptoms?
