OK I have a 78 Caddy 425 engine in my 37 Ford I`m building. I dont know how many miles are on it. My brother gave it to me for my 37 a couple years ago.I just got it to the point I could start it last summer.After putting a new set of wires and plugs on it it runs good.I installed a cheap mechanical oil pressure gauge and it would indicate about 40 psi cold and would drop to 20 after it warmed up.Now it starts at 20psi cold and drops about 5 psi after it warms up.To me this seems a bit low.I have a little lifter noise but nothing else.Is this typical of these engines or do I have the beginnings of a grenade?
