This 1985 chevy k10 with a blueprint 383 came in running rough and blowing oil out of the valve covers. After doing some inspection it had low compression on a few cylinders. Turns out it had 2 busted pistons! We tore it down and replaced the hypereutectic pistons with a set of D.S.S racing forged pistons and rings. While we had it apart we upgraded the camshaft with a Howard’s rattler cam and a degreeable timing set! We also swapped out the chrome valve covers for a set of finned aluminum valve covers. We finished off this project with getting the factory a/c charged and working and a quick wipe down with some quick detailer! Looking for running video in the comments.
