I'm ditching the 30+ year old dual plane intake and single 850 in favor of a tunnel ram and dual 850's, even though I've never even started the f***ing thing yet. I need some sort of starting point for the jetting, power valves, and anything else I might need to know to set the carbs up. Both carbs are mech. sec. Holley 850 List #4781.
13.25:1 BBC, .714/.714 lift, .274/.278 @ .050, I'm not sure what else is needed as far as info. Thanks!
