Had a 383 stroker in my 74 Nova. The guy that built it neglected to use loctite on the rod bolts. Short story nut came off, rod cap went under the crank and wedged in a cylinder. Block is screwed as is the crank. Jacked 2 rods that need replaced and 1 piston. When I rebuild it will not be raced on the track. Will just replacing the broken parts suffice or go all new. Any experiences will be helpfull.
