The Stovebolt Site Forums The Shop Area Engine Shop SBC 350 1970's Over heating

I rebuilt the engine about 1500 miles ago. When I start the engine, at idle it is about 7 lbs and if I step on the gas it is about 25 lbs. Once it warns up, the idle is 0 lbs and stepping on the gas is about 10 lbs.
I have tried 3 different oil pumps ( regular, high volume, and high pressure). I have two different oil gages on the engine.

I have an oiler cooler on the system and tried 160 to 190 thermostats.

The compression is 130 to 150 on one side and 120 to 135 on the other side.

I have a new water pump and a rubber hose with metal over it so it should not be colapsing.

The timing jumps between 2 different amounts (I think it was about 4 and 9 ) The dwell I have never been able to set, but I no longer use points but that electronic unit that you put in the cap to replace points.

I have taken the hood off, to keep the engine cool.
