Thanks for the help guys. I had the two end main bearings off to-day and I had one piston out. The 3 bearings were all pretty well wiped but the crank was in excellent condition. The rings on the piston were all intact and the top ring groove was almost clean very little carbon. The ridge cleaned up easily and wasnt really that deep. So I figure rings and bearings at this point. I will be measuring the bore tomorrow to see how much wear their is to be sure its within toerance.

I took the cam out and had a second opinion on the lifters. They have minimal wear and from what I can tell the cam looks good. But I guess what I realize now from this board is this particular cam might not be the best choice. The front of the engine was stamped high performance passenger and I believe it is a 73 block casting. So this cam is meant for an off the lot muscle car in 1973 is my guess. Even if I dont buy a new cam like you suggest I look into Pat, It would make sense if the cam from my rv motor is a cam suited for the rv/truck chassis. The cam has a no. stamped on the end 59G F4 I'm thinking that this no. can identify the cam?
