I have a 1955 MM GB Gas with a 403 cubic inch. And was woundering if anybody knew what the PSI pressure per cylinder is.

The diesel 4214 is 14.9to1 with 440to460 cylinder pressure.4204 is5.9to1 with 95-125 psi. 4204 is a very low comp. head.

What number heads do you have?Makes a difference on your compression.130 to 150 I'd say.

The head number for the MM 1955 GB Gas is 10A4204.
I was also wondering if you can tell me the compression on a 1954 MM GB diesel with the number 10A3006.
Thank you for all your help.
