Just fired up a 383 that was built by a local shop. Ran the initial break in, then an additional 1-1 1/2 hours a couple days later for some carb tuning, timing tweaks etc. Then upon taking the car out for a test drive it quit.
After swapping out the fuel pump with no success the pump rod was compared to a "core 383". The failed rod was 5/16"shorter. The"core" rod is running.
So is it really possible to have a fuel rod fail that quick? We have Brad Penn break in oil in the engine. Should I be suspecting internal engine damage? The motor has no other signs of problems , even the valves are quiet.
