mechanical or electric gauge? the 454 in my jet boat idled at around 700 and had maybe 20 psi and it lived thru hell with me in that boat. 14, if actual is still a little low. what oil, filter etc and is this something new or has it always been low?

Sounds fines to me. Like the old rule of thumb 10 pds per every 1k rpm. I'd just ck it all the way through at all rpm levels but sounds like your fine. I have a built 421 in a muscle car with tighter clearances and rpm to high at idle. Yet I can't idle below 1k. What kind of speeds and power you have. I had the old original red 87 years ago. Fun boat.

they are 557 bbc's based off bulldog 500's. they have about 25 hours on them. 650 hp on dyno. runs 93 on the gps. engines run great but that needle down on the gauge scares me.both engines read exactly the same.
