    Which engine swaps can be done on gmt400

    Sorry on the delay, stopped getting notifications not sure why. Was extremely easy, the sbc I put in it used the same motor mounts and clam shells. Also the same transmission. You'll have to get a tcm or wire a plug for 12v and manual valve body (which is what I run). Also ran a carb and took...

    Which engine swaps can be done on gmt400

    Thought about the 400 route, I have had a 406, Block is weaker all around. They will split webs, cyl. walls, etc. more readily it seems then a 327/350. Finally have some time to sit and research abit more I'll see what I can come up with. I do have a 454 short block with some scat h beams and...

    Which engine swaps can be done on gmt400

    What Im looking for is a stout high revving engine. The 472 i had in the square body was great, but they dont like to rev. The ls stuff is nice but still sluggish without a turbo. To 94_C you dont need to do any programming if you buy a parts truck, if its running you pull the vats fuse while...

    Which engine swaps can be done on gmt400

    They do have the plate and flexplate to bolt it up to a 4l80e, not sure where it would put the cummins in the engine bay tho. May or may not be to close to the rad. Duramax is doable but finding one cheap only happens once in a blue moon (cheap as in under 2 grand) Edit: Also from ontario...

    Which engine swaps can be done on gmt400

    The bbc is very doable, I do have a block/crank/big rods and domed pistons but no heads. And had a 1970 date coded 472 in the last square body I had. I came from driving a 2004 6.0l f350, which i had did all the deletes and head studs and it really put down power, the same as the duramax i had...

    Which engine swaps can be done on gmt400

    I have a 98 k2500 thats been through 3 engines so far. Started as a 6.5L diesel that was rust free. I got it in the dead of winter with a busted windshield and no heater, but it ran good and was abit of a gamble. Barely turned up the torsion bars, and cut the front bumper about an inch of so...

    Gmt400 to gmt800 multifunction switch swap,diagrams needed

    Still been swamped with work and more snow now. To save myself time, I used my old wiper/cruise control part of the switch, they do unclip rather easy. (The box with the plug on the switch) And inserted it on the new switch. The turn signal and hazard part of the multifunction switch seem to be...

    Gmt400 to gmt800 multifunction switch swap,diagrams needed

    Sorry on the delay, I have mine in and working. Have todo a write up. Where I am in Canada there's an abundance of gmt800 trucks and very few gmt400's in the wreckers. It cost me a total of $10 for the GMT800 style instead of the $150+ for a new one here

    Gmt400 to gmt800 multifunction switch swap,diagrams needed

    Looking for the diagram for a 95-98 multifunction switch, All I can find are ones labeled 88-98 and they arent the same pin outs. The switches are physically the same, plugs are also the same. But the pin outs are different. Plugging it in without modifying anything results in the mist...

    Heater question

    It's abit of a mix between the two, it's stuck on the floor but the recirculation button works and air flow changes in sound when it's pressed. And yes I get a small blast of heat then it goes to a Luke warm heat. No matter if it's on cold or hot.

    Heater question

    Before I ripped everything completely apart I figured It maybe easier to ask. I have a 98 k2500 and the heater blows only abit of warm air. Works on all settings for the blower motor 1-4 But the vents dont change, seems to be stuck on the floor vent. If I leave it off then turn the blower...
