1st gen 5.3/4l60E swap ???

Spnknu · 09-24-2009, 01:39 AM

I did a search on this and didn't find what I was looking for so bare with me.

I'm considering swapping in a 5.3/4L60E setup into my 1992 Sonoma GT. The truck already has a 72' 350 SBC swapped into it by the previous owner. My questions are:

1. Can I get a wiring harness that utilizies the factory gauge cluster?
2. Can I retain my a/c and cruise with a DBW system?
3. What type of gas-mileage can I expect?
4. On a scale of 1 to 10 how difficult is the swap?
5. Any suspension issues I might encounter with the swap?

Right now I'm trying to gather as much information as I can on the subject. I've considered using a 5.3 truck block with corvette accesories and mild bolt ons. I would like to keep the interior & exterior fairly stock to retain the "sleeper" effect. The purpose of the truck would be just a road warrior in the sense that it would be driven daily and would have to be reliable. Any help or input on the subject is greatly appreciated.

Later

Clay is right, Current Peformance did my harness all my gauges work fine and it has cruise built in even though my truck never had it, I picked up a colum with it and just have to run a power feed the other wires are in the harness so yes you can keep your accessories. you will need to have custom ac lines made for the gen 1 setup, I haven't got that far with the ac I am still waiting on an aftermarket condensor from Hot Rod Air.....no suspension issues....it is a techical swap for professionals only so "don't try this at home"...jk...there are enough people who have done this so all your questions can be answered by a search or just posting.... good luck
