Phil just so you know you are not the only one that picked the wrong builder. I used one long time ago who rebuilt my motor and said it was the fastest buick he had ever been in. I picked up my car in winter and there was no heat, i got home called him and he said put more antifreege in the rad. I did and thought all was well however still no heat, he had the boost pegged and blew the head gaskets, i was so pissed i sold the car cheap just to get it out of my head. Hopefully you won't have to do that but i was just frustrated to the point the car had to go.
