Firstly, I've searched and dug through threads and can't get a clear answer on this. Your knowledge is greatly appreciated.
I bought a non-running truck, and after messing around a while noticed the harmonic balancer moved like a cam while cranking.
I tore the bottom end apart, and the mains are spun and the crank is roasted pretty bad. I think the block is ok and I'm taking it to get checked out soon.
Got a used LBZ crank, and my question is if it needs to be balanced with all the old pistons and rods, or if it's fine to run with the LB7 harmonic balancer and flex plate. I'm not planning on keeping the truck, it's got just over 100k on it so I want to fix it right and sell it again.
I'm not planning to replace anything except rod and main bearings, unless, of course, the block is shot.
The oil pick-up tube is broke completely in two and bent as well. No idea how it happened, but I'm guessing it contributes to the spun mains.
