jimmy21669 Posted January 22, 2011 Share Posted January 22, 2011 So, my 2.5 is a little tired, and I have a 4 speed with 3:55's so it is a dog. I have an opportunity to trade my 2.5L drive train (AX4 and 231) for the drivetrain from a 94 S-10 (4.3 TBI, auto, 231). Straight up trade. Question: Has anyone done this? Does anyone have any input on things I need to know in advance? This engine was on my short list of engine upgrades since with the Chevy bellhousing I could use an SM465 Muncie 4 speed behind it....but I want to know what to watch out for and how hard the swap would be. Would my cooling system be adequate? Etc.? Thanks for you quick input! Jim Link to comment Share on other sites More sharing options...

kyleag89 Posted January 22, 2011 Share Posted January 22, 2011 I don't know too much about the swap but, you would need the wiring harness and ECU from the S10 also. I would think you might wanna look for a complete parts truck to have everything you need. Why not just pick up a complete running H.O XJ with no tittle for 500 bucks?
