1994 Sonoma SLS wanting V8 swap advice

15

Asked by weemerman Jul 20, 2021 at 01:54 AM about the 1994 GMC Sonoma 2 Dr SLS Extended Cab SB

Question type: Car Customization

I have a 1994 Sonoma SLS 4.3 Vortec and a 4L60E tranny. Its a "W" truck
with the 200hp v6 and Central Port injection. I have a 1st Gen 350 ready to
go in but not sure if I need to change over to Fuel Injection so the computer
will work? I recently found out without the computer many things will not
work. Anyone with advice on fuel injection or how to adapt my 4 barrel carb
to work with the computer?

If your state requires the truck to be smog legal you will need a 1994 or newer engine with all the smog hardware that it originally came with.
