Isn't that upgrade spider set up, very expensive? Been a long time since in the shops, so I am unsure.
I did the swap a few years back into a 1989 Silverado. Pretty straightforward but there are some special items needed...I have a 1993 k1500 with a tbi engine an I got a 1998 vortec engine an I was wondering what am I gonna have to do to put that vortec in the 93 Chevy

I bought a crate engine from Jeggs and opted to retain the TBI with 1989 computer and wiring. Harris Chips out of NC burned a chip for my ECM so the TBI will run correctly with the Vortec camshaft profile. They have several options for their profiles. I also got a higher pressure fuel pump kit (stock GM Vortec era pump with TBI pressure spring upgrade) from Harris at the same time. I would recommend the fuel pump upgrade even if you do not do the swap,
GM makes a TBI to Vortec aluminum intake. Pricey but pretty much bolt in. Others have used a carb intake with a TBI adapter; I used the GM intake - looks factory. Original throttle body, distributor, coil, oil pressure sender, etc are direct bolt in.
EGR on Vortec intake is in a different location requiring the driver side exhaust manifold and EGR tube from a Vortec engine. I had a boneyard donor for that. Original EGR valve works.
If you stick with TBI, the crank sensor hole in the timing cover of the Vortec engine has to be sealed. I left a crank sensor in the hole with nothing connected to it, no leaks or issues so far.
I changed the O2 sensor to a 3-wire heated sensor. I added a 3-wire plug, used the stock sensor wire and ran a ignition on power and ground. The 1-wire O2 sensor will work but 3-wire gets to closed loop faster.
I run my timing per 1989 TBI specs - seems to be working just fine.
My truck did not have the factory oil cooler setup to the radiator but my donor engine did. I swapped that over with new cooling lines and new {bigger} radiator with the factory oil cooler setup.
No changes to engine mounts, exhaust, radiator hoses, heater hoses, A/C mounting or routing, alternator, water pump, fan, power steering - all of my accessories mounted right up.
