Here's what that page spits out for my current compression/cam
Quote:

Your dynamic compression ratio is 11.21:1 .
Your dynamic cranking pressure is 244.55 PSI.


So it's safe to assume this WON'T run on pump gas



LOL

i know a guy a couple miles from me with an iron headed 390 and around 225 psi on pump 93.

But 244...likely not.
