Anyone have any idea what Holley carb (new) would be best for a 534? The Holley website suggests a vacuum secondary 570, but the calculator only asks the cubic inches and rpm of the engine. I'm wondering if a 534 being the beast that it is has different needs than a "normal" motor. Its got a vacuum secondary 3310-2 750 on it now and runs poorly, starts hard, and uses a disgraceful amount of fuel. Time to throw some money at it and buy my way out of a recurring headache. Hopefully one of you guys has the answer!!
