I recently swapped a 360 magnum out of an 01 Duragno into my 1980 Volare. I used a professional [products air-gap intake in order to run a carb, a used holley 4160 600cfm with vacuum secondaries. The fuel pump is a holley mighty mite, making around 7 psi. but I've got a regulator so I can change that now. Other than headers, intake, and thinner head gaskets, the motor is completely stock. It has a big flooding problem. at first it would run extremely rich with black smoke and everything. I got it leaned out enough to get rid of the smoke. But, it still runs horribly with rough idle and hesitation/stumble above mid-throttle. WOT runs good, leading me to believe it still runs rich. I've also had a problem with gas in the oil. I rebuilt the carb and ran it once. It wouldn't idle at all, even with the adjustment screw all the way in. It had gas in the oil AGAIN afterwards. It also read only 3.5 fuel pressure with the regulator all the way open. I'm completely confused on what the problem could be, I have the carb off now and I'll look at the idle circuit and check things out again, maybe test the fuel pressure without the carb on the car somehow. This is my first go-around with a holley so any help would be appreciated!
