Hey guys. Im new to building engines but I'm in the process of diagnosing and rebuilding my olds 455. (Que the replace it with XYZ motor comments) I have two engines with various good parts.
Engine A Spun rod bearing but good everything else
Engine B Bad camshaft (rusted). Piston with broken skirt (My fault during disassembly. I dropped it on my foot)
Option 1 replace crank in Engine A with one from B as well as the rod that had the spun bearing
Option 2 build Engine B and replace broken piston (possibly from engine A)
What machining is required for both of these options. What about balancing?
Im not building a snarling beast. Just a reliable 455 (add more comments here)
