You can put the Vortec in it if you have the wiring and ecm to run it. or you could use the Vortec heads and an aftermarket intake and really wake up your engine. The vortecs use a roller cam.
Haynes repair manuals have good vacuum diagrams
yes i suppose
The 88 engine is a TBI / Throttle Body injection engine. I don't know the month of 1996 when they changed to the vortec engine fuel system, But I believe it was in late 1996. You should know if the 1996 engine is a TBI engine or a vortec engine if you have Sean it. So if it is a TBI engine then you have no problems, Put it in there and hook everything up and your good to go. Now if it's a vortec engine you have problems, None of the wireing will hook up to the 88 engine sensors. And the 96 computer will not run the 88 engine. And the fuel pump in the 96 Tahoe has to much fuel pressure for a TBI engine. You can not put the vortec fuel system/ intake manifold on the 88 engine because none of the intake bolts will match the heads or vise verse. You will be opening a can of worms. You need to go back with a vortec engine if that is whats in the Tahoe now.
they say 3500 lbs i think but i have towed 7000 lbs with good trailer breaks over a distance over 150 k
WEll it all depends on the fuel system on the truck and motor if hey are the same u should be good... but one may be a tbi system and that's where u might need to do a little tweaking on your set ups.

About $14.00 for a good 1.
try having the shift solenoids checked, it seems to be a big problem with the Chevy trucks. my truck is not shifting properly 1996 Chevy 1500 v-6 vortec 4.3 L with automatic O/D . Solenoids are in the pan on the bottom of the transmission. Good luck.
its "not supposed to be if it only jumped one tooth",, Good luck.
Yes you can, But you will have to replace the fuel pump. The 91 fuel pump pressure is 9 to 13 LBS. Required pressure for the vortec to make it run is 55 to 62 LBS. of pressure. The next thing you will have to change to make it run is the compleate wireing harness so you can use the 1996 powertrain control module ( PCM ). You will have to use all of the ignition parts that belong on the vortec engine. Every device that came on the vortec engine must be on it to make it run. The next problem is the 700R4 Transmission that is in the truck now needs the 91 PCM computer to work. Remember you changed it to the 1996 PCM so the engine will run. In other words you will now need the 1996 Transmission. 4L60 or 4L80E trans. Depending on if the 96 was a 1/2 ton are a 3/4 ton. That will make a difference in what transmission you will need so the 1996 computer- PCM will shift the Transmission correctly. The GOVERMENT does not want us modifying anything anymore. And that is why you will need everything that it took to make the 96 engine run. Good luck, I would like to know how it works out for you. NEUTZ.
you might have a bad coil or you might not be getting 12 volts from ignition switch check your fuse box under the driver side dash good luck
A GM Vortec 305 4.8 liter engine has a rating of 315 horsepower. It is not good for towing, however, having little torque on the low end.
