ps- its not smoking and i have a holley electric fuel pump.

Sounds like you could have a bad fuel pressure regulator.

What it usally is is stuck floats. If the fuel pressure is to much for the floats they will not seat properly and the fuel pump will continue to pump fuel through the carb past the intake through the valves past the rings and into the oil pan. When this happens you are wash the cylinders with gasoline which is very bad. The oil also breaks down and is no good anymore. I assume since this is a 85 you have a carb. Pull you air filter and watch how much gas continues to flow after you shut off your car.

btw i think that holley 750 is way over kill for your engine. You probably are running way rich aswell. Bet you would make more power with a properly tuned 650.

Float performance and float level are critical in carb'd cars. Set the float level too high, and the gas will boil out of the carb when you shut down a hot engine. A bad power valve will do the same thing in some carb models. The gas ends up in the crankcase after washing all the oil out of whatever cylinder is physically at the lowest point below the carb. The clue is that the car is hard to start when warm.

A 650 would probably be a better choice for a carb.
