Hi All, I've searched to try to find this here, and I bet it is, but i just cant find it. SO....
At start up and cool engine, I get about 30 psi. When I get it up around 2500 rpm, I get about 50psi. But after I drive for a while( maybe 25 minutes) when I come to a stoplight, I drop to about 5-10 psi at 850-ish rpm. I get back up to 40-50 when I accelerate hard again to 2500. That feels scary to me, but is that normal? Fresh oil, new filter.
'68 400HO Coupe, 4 spd, 259 interior, Windward Blue. My other car's a Johnson 15 outboard on a '61 Starcraft rowboat... Just sayin'.
