My Jeep has a 350 sbc. IT is a 77 block with vortec heads and a serpentine belt system and I currently running with a 670 Holley Truck Avenger. I would like to change over to the factory GM TBI system. My transmission is a TH400. I am looking to purchase the complete wiring harness with computer, sensors and Throttle body. Can anyone tell me about how much $$ and I looking at for purchasing all of these components? Heck if you have one available for sell let me know. Thanks!
But you can buy everything you need off a 350 and modify the harness and bolt it on yourself for probably less than 200.00. I have some photos in my build thread showing the modifications to a factory harness to run TBI on my 258, you will basically do the same thing to run a stand alone system on your 350. You will need an adapter or a TBI intake.

I have what you need if you're interested. All components and an aftermarket wiring harness with computer that fits. Message me if interested in it. It was installed on my CJ but I went to a Gen II Vortec so the TBI stuff is surplus. All from a 1990/1991 Chevy pickup truck and can be used with automatic or manual transmission. Manuals included.
