Here is a used 350 tbi unit.It came off a running truck. I have done the tbi mods to it but never ran it myself. The top of the bowls have been smoothed flat, the butterfly shaft has been ground done and smoothed and the pressure regulator has been made adjustable. It is set to the max pressure right now which is in the 15-16psi range. It can be turned down with needle nose pliers while on the truck with out taking anything apart. The 3 bolts are included. $85 shipped to the lower 48, OBO. paypal
