How much compression loss can I expect with a high lift cam during cranking? I fitted a genuine euro high lift cam on my 1500 during a head refurb and can't get it started. During running basic checks I checked the compression and I'm only getting about 700KPa which seems very low to me. I'm just cranking with the plugs out. I never checked the compression before but it started easily and ran fine. I've rechecked the tappet clearances and they are fine.
