The first time I ever tried an 80 psi pump the new engine started and ran then quit. Pulled the distributer cap off and the rotor wasn’t turning. Pulled it out found nothing wrong. Pulled a valve cover off and the valves were not moving. Found that the key on the cam sheared. Replaced the key and it start up an ran, when we rev’d it up the cam key sheared again. Grrrrr...20 some years later I can smile about it. We weren’t back then. We pulled the engine and put in a 60 psi spring and never had any trouble after that. Not saying it will happen to you. But Pontiac didn’t exactly overbuild the cam gear or the cam drive.
