ok, time for an actual tech question

Whats the first and last year that GM used TBI on its 1/2 ton and up v8's? and were there any significant changes throughout the run?

They were introduced in '87. Half-tons stopped using them in 1995 when Vortec was introduced, but I think some 3/4 - 1 ton trucks and vans still used TBI, but I'm not sure when they stopped using them. :)

well i know that my 83 chevy wasn't running t.b.i., i believe it was the p.o.s. version.

1996 marked the switch between TBI and Vortec engines. Vortec engines made it into all GM trucks at that point.

So its 1987-1995 for the TBI motors, with no significant changes along the way.
