302 Carb'd or 5.0EFI?

Well, I have been tossing around the idea with my step dad about putting a v-8 in the ranger ever since i got it. Now with the lift and 35's, not sure if the 4.0 is gunna be able to push out enough power. Besides, Its just cool to have a V8:) lol. At first i wasnt sure it was possible, but after going through some of the threads on here, i have found it is, but its ALOT of work.

So, heres my question. My dad said if we do it it should be a Carb'd 302. But, from what i have heard, the newer EFI 5.0(yes i know, same thing as a 302) is better. I have NO IDEA what would make it better.

So, give me some ideas, advice, whatnot. How much work is it really? roughly, how much money am i looking at?

btw, truck is a 2000 xlt 4X4

i would find a donor 5.0 explorer and just use everything from it.

do some searching, you will find all of the information you need on the swap.

im not sure, i would rather have fuel injection and obd2.
less stuff you have to worry about, and you still get to use your stock instrument cluster (check engine light, etc).

look on www.craigslist.org and if that doesn't turn up anything, check on www.car-part.com for explorers with a 5.0 engine, then pull everything you will need.

351W is the same block as the 302 so that would also fit. If I was doing a V8 swap, I would do a carb and a bored out 351w or carb on a roller rocker 5.0. I ran an efi 347 in a mustang and I rather have the ease of a carb any day. Let’s compare pros and cons of card vs. efi:

Pro efi:
- will not flood while on angle
- easy start up in winter
- lots of tuning options with correct equipment
- better mpg on avg.
Cons efi:
- harder to install
- set-up more expensive
- need expensive equipment to tune
- more parts to brake
- harder to diagnosis problem
- limited performance options on explorer 5.0
- limited engine options

Pros carb:
- much cheaper
- many performance bolt-ons
- more engine choices (302, 351w, roller 302)
- very easy to tune
- cleaner engine bay with less wires
con carb:
- may flood
- harder to start in cold
- mpg may be lower


If you really had money, you could buy one of those efi kits that replace the carb and has its own computer and then have the best of both worlds…lol. Idk, for our Rangers, I would take a carb set-up over a explorer 5.0 any day.

Yeah, I know i love the sound of the carb'd 302! ITs AWSOME. and i love the clean look of the engine bay.

but then he would have to figure out how to make his instrument cluster work.

im talking, speedo, tach.. everything..

i would rather have my truck be a reliable daily driver then save money and go with a carb.

dropping a 351 with a carb would be great if he had a 94 and earlier (pre obd2) ranger, but being that he has a 2000, it would be a lot more work.

stick with the oem explorer setup.

4,950 cc 5 liters 8 V engine with 101.6 mm bore, 76.2 mm stroke, 9.1 compression ratio, overhead valve and two valves per cylinder.
-
Fuel economy EPA highway (l/100km): 12.4
-
Power: 160 kW , 215 HP @ 4,200 rpm; 288 ft lb , 390 Nm @ 3,300 rpm


if you go with the headers like bob used, it will free up a crap load of power.
you can't use long tube headers because of the limited space, but the stock manifolds on the explorer 5.0 are garbage.

302 vs. 351W

First, the 351W block has a 1.3" taller deck height than the 302, making it both taller and wider. You will have clearance issues especially on the passenger side.

Second, the 302 Explorer FEAD is much more compact than the stock 351W FEAD because it is designed to fit a Ranger sized engine bay. Using the 351W FEAD would make the engine longer right at the front where there is no room.

Like anything else, a 351 swap could be done but would it be more work.

If you plan on wheeling the truck in any kind of off-camber situations go for the EFI(trust me on this). The 351 will fit, but it is taller and wider(the deck). Headers/exhaust becomes a problem. Mounts are the same and you need the same oil filter relocator kit with the 90 degree adapter(to clear the steerin box, at least on the 84's you need one). I have a VooDoo cam in the 302 thats in my 84 right now and its a 351 profile cam(the truck growls). Study up on the swap, as they are time consuming. Keep us posted.....

they changed the ranger in 98, its almost impossible to squeeze a 302 in it as is, i would hate to see how tight it is with a 351.

All of the advise given here is good. I didn't do a swap per say so much as a 1 for 1 with a 98 motor and tranny in my 96

A carbed swap may seem easier and cheaper but like any project, take what you estimate as what it is going to cost you and tripple it. If you go carb, you have to completely do away with all functions of OBD, switch your tranny to a non OBD auto or a manual. Preferably one with a speedo gear in it so you can drive an aftermarket speedo. You can completely replace your insturment cluster with aftermarket gauges but it just adds to the complexity. You will also need to run a non EFI fuel pump and get a gas gauge sender that works with an aftermarket gauge.

My suggestion would be to find a rolled 98+ sploder doner or a non-runner on craigslist. Also try calling insurance companies and asking them if they have any in "inventory." I bought my rolled Mountaineer back from my insurance company for $850 so that I could use it as a doner for my 96.

The wiring for the OBD2 on an explorer isn't that bad. There are 5 main sensors that make things work. Cranshaft and Camshaft position sensors, MAF, TPS and Upstream O2 sensors. If you do a 1 for 1 swap of all the nescessary components, you won't have to do any tweaking of the PCM. It is when you start swappong things like fuel injectors and MAF's that you will need tuning.

One thing that you will have to be mindful of is the PATS system. You MUST swap all PATS components or delete/bypass them through tuning. This would not be nescessary if you were to find a 96-97 doner.

I'm not sure where the speed sensor is on your ranger, but on a 96-97 explorer, it is in the back of the transfer case. On a 98+ explorer it is in the rear housing. Therefore, if you use a 96-97 you can get away with just switching the tranny wiring harness. A 98 + would require you to to run speed sensor wires to the rear or possibly even require you to swap out the rear.

One more difference is the fuel canister crap. You will need to either use that from your ranger, swap it from your doner or delete it through tuning if you use a 98+.

I did a lot of this research myself about this before I bought my the Mountaineer I had and decided it would just be easier to go with one that came OEM with a V8. :)

Good luck.

ok, A 351W for be hard to make it work, but it could fit. They even made a Lighting's 5.4 fit in a Ranger which is much bigger (wider) but you'll be doing a lot of fab work.

Yup, I've even seen 460's wedged into Rangers. It all takes time, money and innovation. The bigger you go, the more of each you will need.
