    2003 with Carb 350?

    I have a 2003 2WD Blazer LS with 4.3 and 5spd if I get a carbed 350 it will bolt to my stock tranny right? My other concern is will I lose any features going from efi to carb or is the engine separate from the rest of the electronics

    it would bolt to it, but then theres no way for a computer to control the transmission. You'd need a transmission computer just to control the trans

    I have a 2002 5speed w/389 sbc, just be selective when eliminating any wiring from the fuse box that goes to old Computer controlled switches or sensors. Computer will not do anything about the 5 speed trans. although the speedo is computer controlled.
