Are you running a restrictor in thermostat housing?

4 degrees advanced that must be numb and should runn cool with no timing.

I tried to retard with the distr. but that didn't help any, maybe go back in and set the timing to dead zero? This motor runs great, awesome power just runs too hot.

I seen this before. Ended up being the wrong head gaskets.

you seem to have another issue here with incorrect timing or you dont know what u are setting it at. A performance sbc will not run at zero or 4 degrees base timing. Do your headers glow orange when you run the car at night?

No they don't glow, the cam I have (Erson 453 lift) was matched to the build of the engine by a local speed shop and Erson said to set the timing 4 degrees +. I have a timing tab that gives a 4 degrees advanced tab, at 1000 rpm I show dead 4+ with a timing light. Am I missing something with this?

I made sure to check the gaskets during the build, I have been through that before as well, also with intake gaskets. I have even went as far as to run 40 below water treatment (two bottles) no sign of change. I am thinking possible flow issue, Heads were rebuilt by a performance shop.

what is your total advance? Did you varify TDC on your pointer (with a degree wheel)when you put it together? I bet that thing gets in it's own way coming out of the corner...
