I would start with Stock Jetting ( usually around 72 ) and use a powervalve that is 2 numbers above the idle vacuum ( in gear if its a automatic ) , always err on the rich side to start
Brian, I would start with 71 main jets & .031 accelerator pump & power valve @ 8.5 only if your idle vacuum is at least 10"
You really need metering block mods such as idle orifice size & PVCR orifice.
Aim for 14.7 cruise & 12.8-13.1 WOT & low speed transfer cruise 13.25-13.7 for better mileage & smooth operation. Bill
