The performer intake is a real turd on a 360 want to go slow use it. I would run a stock cast iron one before I would use that intake period. By the way if the edel is sitting on the intake without a 1/4 spacer part of you pig rich problem is just that. get a 1/4 carb gasket set carb as above and some of the richness will be gone.That intake loves to leak at the base of the carb and that is even when brand new!
