2006 gmc 4.3 to 350 small block

Recommended Posts

I have a 06 GMC Sierra 1500 with a 4.3 and found some carb swap hits to do away with the spider injector but I would rather swap a 350 or build a 383 for it. The truck is a basic single cab long bed work truck edition so no special electrical components other than the radio cluster and an airbag under the seat. How hard would it be to swap it for a carbed 350? Was thinking maybe the computer and everything from a 93 or 94 Chevy since it has the 4l60 in it and could splice my trans connector into it. Thanks.

A 93-94 engine/computer runs a TBI system, you couldn't use that with a carb.


Either you go with zero electronics other than the stuff to run the ignition and something like a 700R4 with a kick down cable or you pick something than can do a EFI carb setup with transmission control. I think Holley sells something like that.
