The best way to find out what you have is snap a pic and post it up, someone will know what it is, people like Mark N. that has his hands on these old trucks every day can usually tell what you have just be looking.

If you are into the free pump mods, hand grind the fuel plate. There is cheap power to be had there.

Hey Mark, look closer. That's turbo has a waste gate. HX35 probably. Is that water injection, or just were they tapped the boost gauge?

Blocks on the front axle I believe may actually be illegal in some states. But they aren't good for handling, legal or not. I thought of that once I saw the post about the extra blocks in back, looks like it might have springs in front, but a good thing to check.

Posts sorta old by now, but thought id give a lil update to those interested and maybe get some more answers.

-The front is all spring lift with those wedges in it to help out with the d-shaft angle. Every thing seems to be skyjacker.

-The front d-shaft that came with the truck wasn't exactly right, had to have it cut down (whole new pipe welded to it actually since I left it in the bed on the way to the driveshaft place)and find the right u-joint and she bolted right up

-The rear does has a massive block on what I assume is the stock lift block. Ill fix it proper one day.

-The more I look into it I believe this is just a P-Pump swap. The lift pump is bolted to the motor still and a piston pump is installed in its place, looks newer than everything as well. And I'm %99.99 the switch on my dash opens/closes the fuel shutoff solenoid (truck will run with the key out of ignition, switch shuts motor down)

-Electrical gremlins breed in this rig. My brother-in-law and I took out at least 40-50ft of useless/unhooked wiring. The switch that lights up the additional gauges (boost and EGT post turbo) is the SOLE means of me turning on my rear parking lamps(blinkers/brake/reverse lights work fine).

-Speed-o-meter wont work. Put in a new speed sensor, still nothing. Me thinks its is the PCM somehow, unplugged it and started her up, idled fine, couldnt find power at the connector either. but the truck charges fine, lack of AC compressor doesn't help.Speed sensor is a 2 wire and the Neutral safety is 3 wire if that means anything to someone.

-Unhooked the stock mirrors and bolted on some junkyard find Mack mirrors.

-Found a Rad shroud out of a junk 93, gotta massage it a lil bit to clear the fan but it fits the Rad fine

All in all thought Im pleased as a peach with it. Definetly gives me something to do from day to day. Ordered some new wheels and tires, even put a proper BHAF setup on it.Been driving it everyday, runs without a hitch. I was really surprised this thing will bury the boost gauge if I want it to.

Only question I have now is cruising down the highway at ~65, I run about 4-5 psi boost and my EGT read ~550 steady, hottest its ever been was ~650 beating on it. This seem normal? Above/below what it should be?

stripped speedo drive is the likely cause of your speedo trouble, but make sure the VSS has ground before you dig in further.

Is the probe after the turbo or before? That seems pretty low. When you get on it good, you should see at least 1100° - 1300°+ if you stay in it.
