Re: My Build Thread (Sort of)

Couple of hundred more miles and I was not happy with the way the truck ran. It seemed to run hot and was underpowered compared to a big block I had owned in the 80's. So I found someone I trusted to rebuild the engine. I don't have the space, tools, or experience to do it myself. Once torn down we discovered 6 402 pistons and 2 396 pistons, 4 burnt valves with bent push rods, and a crank that was so far out of tolerance it couldn't be turned. Just behind the rear lobe on the cam there was a grove cut all the way around. Believe it or not the truck actually ran ok and didn't skip at all. My mechanic has been rebuilding engines for 30+ years and was amazed it ran at all. So the rebuild begins.
