I've had 140's on a fresh engine...dunno if that's what stock would have been though.

Cool questions.
It'd be interesting to see some tables covering those on a bunch of engines.
The cam and it's timing has a big effect on it too as you prob'ly already know.

after viewing several engine cranking pressure Ford basically has engines that are 130-150 psi.

No LESS that that
