This is an FYI
In my 9.8:1 SCR, 7.9:1 DCR 383, cranking compression with a run of the mill heavy stock GM starter was around 180 psi.
I bolted on a Delco style mini starter that cranks noticibly slower, although still starts the engine within one or two revolutions.
Cranking compression decreased to 150 psi.
I have less than 600 miles on the motor. I checked leak down at around 300 miles and was less than 3% across the board.
