S104x4.com will have a ton of info for you, if it is still up, been a while since I had my S-10. Also, a book by Jags-That-Run has all the info needed for you to. Try a search with that name and it should bring up their website. Have Fun!

S10-4x4.com is dead... Has been for years. Most of the people from that site have gone to another...the link in my sig. s10-4x4.org That will take you to an EZBoard site we are using until we get some server issues worked out. S10-Extremists.com

A book you should not be without is the conversion manual from www.jagsthatrun.com Parts lists and step by step details of what you will need.

There are tons of people that have done the swap. People just as crazy as we are. If you have any real technical questions, post them over at that S10 site and someone will know something.

I think it was Fourwheeler that did an article on a 350 swap a couple of years back. I know they ended replacing the transmission, transfer case, and rear axle. however I think this might have been a fairly built 350, but I can't remember. anyhow I'll have the rear axle out of my ZR2 for sale in a couple of months. It's got 3.73 gears, disc brakes (99') model, and a gov-loc, but that can be eliminated. you can have it for $100 when I take it out.

If you are wanting to swap in a v8 that is already set up for TBI then just unplug your current wiring harness, but do not remove it. Put the new motor in and make sure you have all the correct sensors for a standard 1988-1991 TBI motor. Plug in your factory harness to the required sensors. Get a v8 EPROM chip from the local auto parts store ($65) for a 1988-1991 TBI 305. Pull the 4.3L chip out of your computer and plug in the new chip (unplug the computer before doing this, just in case). Make sure there is power (battery juice).

Crank her up.

Not on the subject of wiring, but you are gonna need a different oil pan to clear the front differential.

Or just use a BFH like I did. Ugly but it worked.

If you have an SFA then you can run the stock V8 oil pan. I have a buddy who is doing that right now wiith no problems.

A gov-loc is a traction device similar to a posi or limited slip.
