So picked up this 91 a few months ago and have been trying to fix it up the 305 needed replacing so I got a 1996 vortec 350 it has the stock Chevy 1500 TBI setup and I would like to know if there's a wiring harness and ECM that could work with mine and I could just run the gauges off the old ECM alternatively I can swap it to a carburetor but it might not clear the OEM hood I want to put on it or I can buy a EFI system with built in ECM.

I would definitely purchase a vortec tbi intake and put the tbi back on the road

 

The engine will bolt in/up fine to everything less the intake. The vortech heads require a vortech intake bolt pattern. The intake currently on the engine is pretty high and likely wont fit under your hood. You probably can find an aftermarket intake that will fit a stock tbi and has a vortech bolt pattern. If this isn't an option, some kind of a adaptor plate for the tbi to mount on a vortech intake. Once its all bolted up you'll likely need larger injectors on the tbi plus a custom prom chip.

another option is a stand alone efi system. Think about the price of getting all the tbi parts and if you have access to someone who can help tune it. Is a stand alone efi much more money? There are people on this forum who can do all that tuning/prom stuff. Those tbi systems are totally limited airflow wise. A stand alone efi will absolutely have more power potential if tuned well. Just a thought.

 

Go EFI in today's world of plug and play systems carburetors are for the people that can't figure out EFI

 

Yeah I'd say that's me tho I'm 20 trying to fix my car in a driveway so I can gtfo

 

i did my first efi swap in my moms driveway. And the first manual trans swap, and another trans, then a rear. It was less than ideal to say the least. I was so psyched to have garage later.
