is the divider plate properly spaced from the impeller on the water pump i know from experience if its not close enough all the water does is kinda slosh around by the pump and almost none makes it through the engine had that problem

i wish it was somthing that dumb i just checked the timing andit is 6 btdc and my timing light says to run at 2k to check the advance so it comes to 12 plus the 6 initial time and it comes to 18 total with the car running at 2k wile i checked the adv timeing it got to 215 deg and stayed i hooked up vacumn adv and it was still 215 so i held motor reved to about 2700 rpm and it came down to 213 deg then when i let it go back to idle it shot up to 230 and when you let of gas it would go to 0 oil pressure for a second and then come up to about 5 lbs so i shut it down

I question your timing checking. At 2000, 12BTDC or 18BTDC is not enough. Run the engine to 2500 and set advance with vacuum pot unplugged at 36BTDC. The retarded timing will cause excessive cylinder head heating.

The low oil pressure is troubling.

you said its all new so im assuming its just been rebuilt if thats the case how far has it been driven since its been rebuilt have you changed your break in oil yet that may fix your oil pressure for the most part.. is your radiator new or is it the original ...

If your tri power isn't new it might have come off an old 421. Way to rich for a 389.

Running rich is not causing your over heating problem.

baadgoat, have you checked the total timing? If your mechanical, or vacuum advance is not working, it would cause over heating because of slow timing.

A vacuum gauge is what you need if you want to get it set just right or as good as it can be. aim for 20# of vacuum at adle speed or as good as you can get it if you have a HP cam in there.

It sounds to me like you have a brake line that is too close to the exhaust.
