Technically, yes. But the previous owner pruned that out of my truck, so we stepped it up a little. LSeverything right??

If you are on IG, search Squarebodybrothers. Any post he has about yanking the TBI has Larry putting his .02 cents worth in.
GM was still using TBI in 1995. I'm no mathematician, but I know that wasn't 25 years ago.......

GM was behind the times in 1995. 25 years ago was the tail end of the 1992 model year. MPFI was easy to find by then. I can't rattle off when the first MPFI system appeared, but I know that Ford was using it by 1986, by which point GM was just bringing TBI to the SBC line. An entire generation behind.
Yep it's true. GM hasn't lead from the front in terms of induction development for DECADES
GM was using TPI in 1985.
The Corvette and F body were both using TBI in 1982.
GM sold more trucks than Ford in 1992-1995 even with TBI.

I like to not argue with Martin.
Solid points. Here's a few other GM fuel injection milestones.
The first electrically controlled fuel injection setup in a GM car was actually on the Cosworth Vega in 1975.
The Buick 3.8 got sequential port fuel injection in 1984, a year before the Vette and F-bodies got the TPI units in 85.
Right around the same time in the mid 80's the FWD GM cars went from TBI on the 2.8 v6 went to MPFI, with the 3.1 coming in a couple of years later with a similar setup.
4.3's went to an optional Central port FI setup in 92 in the S-10's.
Let's not forget that GM was the first to come to market with Mechanical fuel injection setups in 1957 on the 283 small block Chevy and as an option on the top of the line Pontiac engine.
Almost forgot... GM was the first domestic manufacturer to come to market with Direct Injected V8 engines in 2014 on the new full size trucks and utilities as well as the C7 Corvette. This is after they had been one of the first to go direct injection in the 4 and 6 cylinder engines almost 6 years earlier.
Their decision to wait a full decade before rolling it out on the truck line, well after it became commonplace in other models, is the slow-moving attitude I'm talking about. Yes, injection was around long before it was widespread. But some manufacturers made better use of it than others.
Sometimes I'm a glutton for punishment.
No, I don't expect to get anywhere, but I'm soaking up the knowledge that comes flying back at me. It's not just trolling, I'm increasing my knowledge base.
Now I know why none of the CO guys will come wheeling with me, I'm the idiot removing TBI from a truck that came with it.

But it's ok as long as you put on another FI system to replace your TBI. Sooner or later the moons and stars will align where I can make it north to run with you northern guys.
It's a start.
It's aaaaaaaaaaalmost warm enough here for me to start up projects for the year. Supposta be pretty nice tomorrow.

Slow moving or tried and true, tested?
GM may have an habit of holding on to long, but they learned when something works to go with it.
The TBI system on the gmt400 trucks just plain works and is reliable as hell. Anyway that doesn't get that is just plain stupid.
Speaking of the gm 3.8 v6
OMG. One of the best engines EVER. produced.
They would give a Mopar slant 6 or a Ford inline 6 a run for it's money...
Did gm hold on to it long?, probably, but they still sold....
Pulled the motor down as far as I am going to take it. I think this was a Pennzoil motor. It is pretty gross inside. There are positives, however. This is a standard bore engine, all of the cylinders look great. I posted a thread in the garage https://ck5.com/forums/threads/where-do-193-heads-crack.329760/ about my cylinder heads, and I think I was just expecting them to be bad. After cleaning them up I do not see any cracks. I am going to need to have them surfaced though, the head gasket was showing signs of failure between the 6 and 7 cylinders.

GM has never felt the need to hurry up and develop anything. They are still spanking ass with a in block bump stick while everyone else is moving up to DOHC. Which is hilarious.
It really butthurts the Ford guys when their boosted DOHC gets its booty spanked by a single cammed NA LS motor. Then it really ratchets up the burn when the LS costed half as much to build.
