I have a ford v8 302 in my 74 (PO did this, not me). Anyway, when I start it up my oil pressure (after market guages, yes they are working properly) is at about 35-40. When it's warmed up and driving it's usually right around 20-25. When I come to a stop it drops to 0 and doesn't rise again until I get into 2nd gear. This obviously has me highly concerned. The oil is fresh, it's 100% synthetic ( I think it's 10w30 but I would have to check when I get home) and I know it's full.

Cause? Cure?

Thanks for the help

Three things you can try:
1) Try 60W oil (20-50W if in cold climate)
2) Get I high-volume (not high-pressure) oil pump
3) Rebuild bottom end of the engine

It is more than likely main bearing clearance.

It's ok to have 10 lbs per 1000 rpm, but not 0. Drop the pan, get some plastiguage, and check the bearing tolerances
