Okay so after all this time i think i've discovered the problem

Now that it's the end of the fall and going into winter im starting to discover the problem. In a previous post i stated that the headers were smoking and the car was heating up fast and shutting down. So i emptied the oil and i discovered it was milky, now the engine was rebuilt not to long ago but used so i know its not the head gasket and im almost positive its not coolant. So i though what could it have been, so i realized when i first started tuning the carb i had no idea what i was doing(being its my first time droping and installing a motor). Well i had the carb all sorts of messed up and the engine was flooding bad, so im assuming that gas worked its way into my oil, and the oil i emptied also smelled like gas. So my question is could this gas being in my oil have caused the engine to heat up fast and the headers to smoke.(also i was positive it wasnt a head gasket leak because this smoke was different from that of which the headers make when coolant is leaking in, also there was not white smoke). So if anyone has any idea please help, also another question which may seem weird, after i put the motor in i started the car or attempted to. and i noticed coolant was leaking out between where the intake manifold meets the head. I noticed that i forgot to put a screw in right there to hold it down, is coolant supposed to be in this area, i have never known the true route of the coolant in the motor, so does the coolant go in this area under the manifold? Again any help will be appreciated.  

Yes, gas in the oil would cause the engine to heat up. Gas thins out the oil, oil doesn't lubericate as well, engine overheats. As to coolant leak, coolant flows thru the intake manifold from the heads. If you were missing an intake bolt it would let coolant leak by the intake gaskets. Good Luck!  

Thanks alot for the fast reply, it made sense to me but i just needed a second opinion. I wanted to figure out of it was worth buying new oil this year and trying it out not that i got the carb set up right. I mean before it was sucking down fuel like crazy, and the rpms would just keep rising. Now i atleast have it to a point where it sounds nice and i get throttle responce. Thanks again  

Bad fuelpump will leak gas into the engine too  

Oh interesting, well when i went to the 350 from the 267 the mechanical fuel pump didn't fit so i got a block plate and now im using an electrical one. If there is anything you think i may have forgotten in the process please let me know. but thanks for the info, intereting to know.  

make sure you are using a fuel pressure regulator with an electric pump. Your carb only needs between 5-7psi.  

+1 for fuel pressure regulator  

Thanks alot guys this also explains some of the problems i was having i believe. Aside from the fact the car is running better now it is still off alittle, the headers still warming up fast(but not as bad). And the engine is still overheating alittle which would seem to be back tunning. I know this can happen when its running to rich. Do you think its possible that because i dont have a regulator on there it could be doing this. The car will start up, sound great then get warm and stall out after about 10- 15 seconds? any help will do, thanks.  

get a guage to see where your fuel pressure is at. Get a return style pressure regulator to so you dont burn up the pump.
The stalling could be caused by an ignition problem. Most commonly caused by a bad igniton module. Is your carb tuned correctly? I have an a/f monitor to help with tuning. They are well worth the 75 bucks. You could get a wideband monitor but those cost about 350 bucks but will tell you your exact a/f ratio throughout the rpm band.
