RE: curious
Compression ratio?
- 1995-2002 is 9.8:1 on all SOHC's.
- 2003-up is 9.8:1 on the Magnum engines, and 9.3:1 on regular SOHC's.
Compression test?
- Should never be less than 100 psi, and within 15% for all cylinders. Mine was around 180 psi in all cylinders after 150k miles or so.
Best of luck!
