Well I finally bit the bullet and bought a fairly new KB 2.3 from a fellow member on here. I also made a call to LFP and ordered a set of 60# Injectors and Walbro dual 255lph Fuel Pumps. I plan on keeping the boost kind of low since I am on a stock block still. Does 12-14 lbs sound ok? The blower is coming with a 3.5" Pulley and I still have my stock crank pulley, a 4#Lower ad a 6# Lower pulley. I'm figuring that I could get away with using my 4# Lower along with the 3.5" to get around 12lbs. Is this theory correct and if not what pulley combo would work?
