anyone have any vac pump advice for a endurance engine, so far i have std evac system but dont have any # as to how much it will pull, not much as i remember. maybe 3-6 lbs vacuum witch is not much. and thats only at high rpms
anyone think one of the new electric pumps would work? i would like to pull around 9-12 lbs thru all the rpm ranges
engine is bbc 4.600 bore 4.250 stroke w/ring pkg .043/.043/3/16 low ten setup oh ya wet sump system
also man are the mfg proud of the belt setups $$$$ big dollars for hp gain 30-50 hp and i was told not very good for enduranc app.????
