    Well first off I would say to make sure you have a motor and complete wiring harness i.e. sensors etc. Next, you will have to either make your own motor mount bracketts or buy a setback plate kit. I would have to say the hardest parts would be that and the wiring. You just have to take it as it comes. Good luck with the swap. This site has a lot of info on it

    Do you have another vehicle to get around in? You'll need one. These swaps take more time than some think.

    I converted my 93 Sierra from 4.3L TBI to a 4.8L LSx. Find yourself the engine you want to use, and I can walk you through it. It's not hard, but it will take you a while if you don't have the parts lined up. I got my swap done in under 3 weeks, and I figured it out as I went.

    I recommend you look for a 5.3L or 6.0L out of a truck, the 5.3's are relatively cheap, and make great power and torque compared to your 4.3L. Heck my 4.8L (280/280 HP/TQ) feels pretty good with my 3.42 gear. If you can get a pull out with trans, you are even further ahead.

    Starting the thread is the easy part.
