This is the first time I have posted here. There are several factors that most people do not mention when they talk about engine swaps. The first obstacle is the government. If you live in california you will have an uphill battle in most engine swaps since you will have to make it emissions legal. You have to find a way to get the engine to work once it is in there. Chevy is the king of any fuel injected engine swap because of the ease of finding aftermarket wiring harnesses and the ability to reprogram the ECU. You must KNOW FOR SURE that you can find the aftermarket harness and reprogram the ECU. Even if you have the ability splice a wiring harness together the ECU may not work since it controls many functions that may not be present in your truck. The older the engine, the easier this may be. Are you willing to spend $1500 on an aftermarket ECU. When you use the Ford transmission will it be manual or automatic. Some automatic transmissions are electronically controlled and may even have a second computer just to control the transmission. A manual transmission will not have this potential problem but you must know worry about shifter position. If you choose this transmission then beware; the newer Ford Ranger is a much smaller truck the the Mazda B series and the sifter may be too far foward, even though mechanics will always have the tendancy to refer to the big Ford and the little Mazda. Look at the Ford engine and take a look at the accessories. Are they on the same side or the opposite side? If on the opposite side then you may have difficulty with A new Air conditioning system. The good news is that the engine should fit fine and you will have room to clear your AC condensor so you can wire the AC. Motor mounts can also be made. If you cannot secure working wiring harness and functional ECU that will work with your truck then be prepared to find a new engine and transmission. If you want a street rod then I would reccomend a 1992-1994 Chevy 4.3l V6. If you want a race truck then I would reccomend a Chevy 350 or a Ford 351. Some wiil scoff at such considerations but these are the things that separate the average engine swap with no AC none of the creature comforts to the engine swap that you, myself and the others here dream of.

I am have purchased a painless wiring harness for my 94 4.3l swap it looks prety easy to install

ya but if you put a 350 in dont you have to notch out the firewall for the distrubtor and wouldnt this have to be done on the 4.3 also or not???? w/ that ranger engine i was going to run a manual trans and i am in kansas so i dont have to worry about any emission crap! and i am not wanting to run a/c on my truck i am going to mount a edc in its place and i did do a body drop of 2 3/4"

Roknmotor, good question. For the 350 you do have to notch the firewall but not for the 4.3 because it is small enough to fit. I think your biggest problem would be to get the ECU and harness to work in the truck. After that the rest may be easy.

ya i think i am going to go and attempt to install the ranger 3.0 since i already have the engine...
