I've been driving my 1989 V1500 GMC Suburban the most lately, but I had been driving this Suburban quite a bit, until the coolant on the carpet started annoying me. I also drive my 1987 V10 LWB regularly. My 1990 K5 needs some work.

On cutting it up?

On the K5
Pulled it into the milk barn tonight and took the intake off.
It rained, so harvest is stalled for a day.
It has been sitting, undriven for the better part of a year. Needs a heater core, and there I'd something wrong that is causing a stumble. Figured I'd install the Holley throttle body I bought for it a long time ago, as well as go against my better judgement and try out the MSD distributor I got with it.
Grinding out the throttle bores in the intake to match the larger Holley butterflies sure sucked. I was going to take some pictures, but my damn iPhone decided not to cooperate.
More tomorrow possibly. Advice on setting a TPS? Never actually done it.

IIRC, you probe two of the wires and adjust to like .54v.

I also think .54 is correct, but I am not 100% sure on that. I know mine isnt exactly perfect due to not having the correct throttle cable bracket on there and it can cause all sorts of little bugs. I also think you will have to reset the IAC to the new TBI unit as well, not hard either.
I ran into somr technical difficulties. I am putting a used Holley throttle body on my modified 350 TBI engine.
It has the newer style TPS on it? Are they interchangeable? If so, what wire to what pin?
Holley throttle body.
No TPS.
A TPS off of a 1994 350 TBI engine I have sitting here.
The TPS off the 1988 V10 Suburban's 350 TBI.
Here is the throttle shaft on the 1988 throttle body.
Cleaned up and bolted on.

All the TPS wiring is is 12+, ground, and a signal wire back to the computer letting it know how far open the throttle is. If you cut and solder the new connector on that fits whichever TPS you need, it will work fine.
You could probably figure it out rather quickly with a multimeter, as I cant find my diagrams right now, or I would just give you that instead.

They are interchangeable, but they aren't 12v . the computer sends out a 5v reference signal. That's one pin, another pin is ground, and the other is the signal back to the computer which should read .54v at itdle
Cleaned up the heads.
Picked up some quality FelPro gaskets, much better than the cheesy paper ones I had last time.
Love the plastic clips to hold them in place.
Need to stab the distributor and button up the rest of it.
Then I have to do the heater core. I hate heater cores.....

Did you ever get the tips swap done? Cause looking at it, can't you just take off that aluminum adapter on the holley, swap the arm on the end oftthe throttle shaft, and bolt the original tps back on?
Not sure. I just bought a pigtail, but I have been sitting in a Freightliner most days, and at the bar all night, so I haven't really gotten around to it.
