I have been running my 72 Ford pickup for about a year with the stock gauges and noticed that the pressure gauge was always on the lower end but never worried about it. Today I installed all new custom gauges and was pleased to see that it idled at 50 PSi when cold... I drove it around the block and noticed that it was at about 25 PSi in gear, which is OK since it idles rather low. I kept driving and it went to almost zero. It would move when revved up to about 25-30, but mostly close to zero.
Anyway, it's a bummer. The motor is still powerful and has actually seen some engine work at one point as it's very clean inside. It uses some oil, maybe a 1/2 quart a week. I have been running Rotella 15W-40. I'd like the engine to last awhile at least until I have a 460 ready to drop in (currently has a 400M).
Would be acceptable to run a straight 50 WT oil in it until I can find the time to put in a HVHP oil pump? It's a daily driver and only in the summer.
Thanks
