Just seem to be a bit low on pumping overall to me. But again lots of things can make that change.

Put some plugs in it, see if she smokes when you fire it up(valve seals leaking/missing)and then let her rip tater chip.


Al, my current engine will pump 90-95 on the first pump and then 140-145 after 5-6 pumps. The compression is 13.7 but the cam is WAYYY different than the one shown in the post above.
The readings are pretty consistent, i would say the engine is healthy as long as it has some decent pan vac, while making a nitrous pass
