Looking at a engine swap from a Ranger to a Scout

[AllanD]

I have a 1962 IHC Scout 80 that I am looking at putting swapping in a 2.9L V6 engine, 5-spd trans, and the transfer case from a 1988 Ranger. Has anyone heard of someone doing this? This should be a good winter project and should not quite double the power output. The engine that is in it has like 80 horse or something like that. Any thoughts or opinions would be welcome as I do not know a lot about this engine/trans/tcase. On another note I have a 1999 Ford Ranger 4 door 4.0L 5-spd 4x4 that I absolutely love.

"Horsepower" is not the specification you should be looking at.

TORQUE and the rpm it is produced at is what matters in a truck.

a 4.0 would probably be OK, given that it produces nearly 40% more torque
than a 2.9 and is making nearly 200ft/lb at HALF the rpm of a 2.9 at it's peak... a 2.9 peaks at 170ft/lb@2600.

a 4.0 is already producing 170ft/lb at 1200rpm and peaks at 220ft//lb.

You MIGHT thing bigger is better and suggest a 5.0 ....

Until someone points out that the larger 5.0 is essentially useless below 2000rpm and doesn't produce it's peak torque until a very 3.0-like 2900rpm.

Sounds like a fun build. I wish I had the facility for something like that. Look forward to seeing pics man!

What is EVTM? That is something that I have not yet heard of.

As far as torque, I think the placard on my Scout says that it is rated at about 90 ft/lbs of torque. So even with the 2.9L (which according to the chart in the tech library) having 170 ft/lbs that is a pretty good increase already. As far as the 5.0, I considered a V8 for about 10 minutes. Then decided that I want something that gives me decent low end torque and power, yet still will give me decent mileage. If I wanted to go bigger I would put a 7.3L Powerstroke diesel engine into this thing, but that would not suit the purpose of what I am wanting out of this build. Thank you everybody for your answers and interest.

Electrical Vacuum Trouble Shooting Manual. Has very good vehicle specific wiring diagrams and gives locations of splices and plugs, which is helpful determining what is what and where the best place to splice things. Would have been lost w/o one on my V8 swap w/ the neutral safety switch and custom dash.

Made some progress

Well decided to work on my Scout today and pulled the front clip, radiator, radiator support, and the left front fender. Getting ready to pull the engine and transmission out to prep the engine bay for the installation of the 2.9L. Pretty stoked. I will also post some pictures of what it looks like. Will post some pictures of what I got done today after it quits snowing long enough to be able to take some.

I hope you will have new pics later with bodywork and painting to protect what hasn't rusted away yet. Beautiful truck.

 

[Eagle_Scout2002]

This is just what it looks like at the start. I plan to start on the body once it can move under it's own power. I plan to paint it hopefully sometime soon after this winter. Plan to do it OD Green. Will definentally post pictures up as my build progresses. I am stoked about this build. It has been so much fun so far, even though it is a lot of work. Have a good one everybody.

fuel system question

I am working on getting all the parts that I need for the fuel system. As I understand the '86 Rangers had two pumps. A low pressure in-tank pump and a high pressure pump mounted just behind the engine on the frame rail. Is that correct. My Scout has dual saddle tanks and I am not sure about being able to put any in-tank fuel pumps in them. Would mounting a low pressure fuel pump just in front of the tank splitter valve to feed the high pressure pump get the job done? Would it be able to adequately feed the high pressure pump? The 4 cylinder engine that is currently in the Scout has a low pressure engine driven pump to feed the carb. I just want to make sure that I will be able to get the proper amount/pressure of fuel to the engine. Thanks everyone.

you can use just the high pressure pump on the frame under two conditions;

1.it must be mounted lower than the tanks so it will siphon feed.
2.it must stay primed.don't run out of gas as this pump will not draw fuel through an empty line.this also means it must be primed at the first start.

Update

Been doing some work on my Scout while waiting to get the 2.9. Hopefully have that next week.

Meanwhile, I am rebuilding a set of axles that I have. Took them off my parts Scout. They are the same thing that I have under my Scout currently, except they are already set up for SOA (spring-over-axle). Someone changed the pinion angles and welded the perches previously. I then did a cut-and-turn on the front axle to get the caster angle to where it should be. The SOA will give me more clearance for the 2.9, as well as about 4-8 inches of lift. Not sure exactally yet. Should have the front axle done this weekend. This will give me Dana 27 axles front and rear. Gear ratio will be 4.27 with Pwr-Loks front and rear. At this point, I am going to go with LT235/75R15 tires. When I can find a set for a decent price, I would like to upgrade to Dana 44s front and rear, but that will be down the road. If anyone wants to, I can go into more detail about what I did with the cut-and-turn. Let me know if there is any interest.

Have a good weekend, everyone.

I'm always into learning. Never can tell when it may come in handy.

Alright then, I will post some pictures and explain in more detail.

Cheap tires? Walmart, or www.treadwright.com gets my vote.
