I just changed from a Performer RPM to a Victor Jr. and the car wants 4 sizes larger jet to achieve the same mid 12 Air Fuel Ratio that ran best on the dual plane intake. The car now has a 79/91 jet combo. This seems like a lot of jet for a Holley 750 HP. The car ran 11.60s @ 115 with the dual plane manifold and weighs about 3700 with me. The fuel pressure is staying rock solid at 7lbs. The HP kit came with a 72/84 jet combo so I am 7 jet sizes larger all the way around. Is this anything to be concerned about?
