Hey thanks for the response... That certainly sounds easy enough and was what I was hoping for. That also goes along with what mortec says about this casting number 14093638 1 piece for roller or flat tappet cams. For some reason I had it in my mind that the one-piece engines were external balance and that their might be some time of clearance issue with the timing set, cam walk etc. I wouldn't mind finding one of these blocks myself since it will go either way. thanks again!
