I am new to this site and fairly new to understanding engines. my first project is a '69 camaro. I wanted some muscle and built a 383. 1000 miles down the road, I had a flat cam on two lobes and two busted pushrods. Never raced the engine. Put in a new cam (crane energizer-same specs) and matched springs to it. Did not overhaul the engine. 500 miles later crank bearings went bad and a piece of pushrod was in a cylinder valley. Had engine totally overhauled except the cam. Mechanic said it looked brand new still. Maybe a mistake. New engine, new ticking that tighening the crane roller rockers doesn't fix. Is cam going flat or was it already? Would a roller cam fix this? My car is down every driving season. Thinking about going to a built 327. Any ideas? I would greatly appreciate suggestions.
