TBI vs. Carb

TBI was NOT a carburetor in any way shape or form. TBI is not bad "generally" such as megasquirt or Holley, or FItech. The big drawback to early factory TBI was the electronics were just not up to modern standards. Jillions of those ran fine until they were driven/ towed to the junkyard or parted

It's a tough decision. I agree that ---- "Likely" not worth the trouble, and if you do have trouble, parts might not be great to find.
