Dropping a 250 into a Bronco

Post #1 by jimmyv65 » Fri May 03, 2013 5:04 pm

Hi Guys,

I am slowly working on a Bronco rebuild. It is a 66 and was originally a 170/6. As part of the rebuild, I wanted to bump up size and stay with a six. In short, I bought a 79 Granada 250. I've been dealing with some of the mods it takes to get this into the truck. I haven't seen a complete list, so I thought I'd start what I've done so far and add to it.

1) Bell Housing/Clutch: You have to move up to the Big Bell and clutch for a 289/302. It all bolts up pretty easy. I reused the original 3 speed trans as it was in good shape.

***Update: The shift linkage from my 3 on the tree linkage needed to be adjusted(bent & cussed at) to properly shift and clear the larger bell housing.

2) Body Lift: I did a 2 inch. I don't have it together enough to say for certain, but everyone says you need the extra room under the hood. It does look like it will be close. I'll measure when I get the hood and fenders back on. I've read some folks getting by with a 1 inch BL.

3) Clutch Linkage: I had to do some cutting and welding as the original linkage is sized for the smaller bell housing. This mod has taken a bit, but was straight forward. I had to cut the pivot tube shorter and re-weld it. I had to adjust the mount for the pivot tube on the engine side. Again, the welder was my friend in making an extra support for the pivot tube mount.

4) Head/Carb Mod: Not required, but I had a machine shop machine down the log and I used the plate that allows a larger Weber to be mounted. I am going with a Weber 38/38.

5) Radiator: I haven't dug in, but it looks like I may need to do something a little different with my radiator. I was going to re-use the Bronco 170 one. I live in Wisconsin, so I figured I would be OK with the smaller radiator. I may look to get a Granada Radiator and mount it up.

**Update: I went with a custom larger aluminum radiator. I couldn't get that motor to cool enough on the Bronco 170 radiator. I had to neck down the output hose from the H20 pump to the bottom of the radiator. Dropped it from a 2.5" to a 2". I bought the Bronco lower hose and the Granada lower hoses, cut them in half & welded up a 2.5"-->2" reduction pipe to connect the two.

6) Motor Mounts: I just bought new ones from Classic Inline. I didn't have to modify.

7) Disty: Not required, but need to decided DSII from the Granada(maybe with an MSD) or DUI. I went with a DUI. It is a very nice unit.

8) Oil Pan: A few options: A) Just run the 250 pan and allow the potential clearance issue to exist. OK for more of a road truck or enough lift. B) Cut and weld the bottom of a 170/200 pan for a bronco onto top/mounting side of the pan. You have to extensively modify the oil pick up. C) Measure, measure and measure--cut the pan at an angle where it would not interfere with the pumpkin and weld on a patch plate. The oil pick up needs to be modified, but it can be done just by bending it.

I did Option "C".


I will add more as I get there.

Welcome to the club!
Hey I really like your mod for the oil pan, can you post pics? My Bronco is driven in northern Nevada and the original 170 radiator has been working fine. Would like to hear driving impressions. What is the axle ratio and tire size?

Oil Pan

Post #3 by jimmyv65 » Sat May 04, 2013 7:47 am

Here's 2 shots of my oil pan during my my mock up. My method may not be as ideal as the full pan swap, but it looks like I got rid of the risks of the pan hitting the pumpkin.

Here's a shot of the finished product.

It has the 4.11's that came with it originally. The tires are 31X10.5's

It may be a couple of months before I can give driving impressions. I am closing down on a the end of a full rebuild project. It hasn't driven in about 18 months.

Clutch Mod

Post #5 by jimmyv65 » Sun May 19, 2013 6:00 pm

The mount I had for the clutch mechanism wouldn't fit on the new set up. The pivot mount wouldn't line up and the equalizer bar was too wide.

I decided to shorten the equalizer bar by cutting it in half and re-welding with about an inch take out. The engine side pivot mount didn't line up on both holes(one on the engine, one on the bell housing). I cut off the back half due to clearance issues and welded up the bar that gave me a 2nd mounting point on the motor for the pivot bar.

Shortened Pivot Mount:

LOL! Brakes and Steer are over rated! I have the brakes done. It was a bit of work getting all that to line up nice with an angle bracket and a hydroboost unit.

I didn't intend for everything on this build to be a modification, but they keep turning up!

How's it going with your Bronco? Looking at the pictures again you did some nice work. Once again that oil pan mod you came up with is only way to go. Waiting to hear how it drives.

I've been slowly plodding away at it. With my schedule, I really only get about 1 day a week with it. It is moving ahead. I am hoping to be done by Christmas...this year. :lol:

I'll get some further pics of the 250 related stuff going on soon.

Here's a pic of us getting ready to take it over to my buddy's paint booth. Time to finally get it all the same color.

Was checking out your build pics again. Looks like a frame off did you have a body rotisserie for that? Really looks good.
What headers are you using? Are those the stock acc brackets for alt, power steering etc? Did the 250 just drop in and bolt to the existing trans without having to move anything around- trans cross member or anything like that?

Looks like a frame off did you have a body rotisserie for that? I just built some wooden "saw horses" and welded up some door braces. It got the job done. You can see some pics of it if you go to this link:
https://docs.google.com/presentation/d/10-wqVwAO3O3QM1C6m8t_v2Tspm7UqIlT7ai1d2aSltQ/edit?usp=sharing

What headers are you using? That is the classic inlines header. It is a nicely built piece, but leave a tight bit of work to get the pipes around the starter and the frame. I am going to have a buddy who is an exhaust master weld it up for me. It goes beyond my basic welding skills.

Are those the stock acc brackets for alt, power steering etc? That is the stock brackets that came with my 250. I thought it looked cool having it all on one side. Some down sides to that though: 1) The wiring harness expected the alternator on the passenger side. It made my radiator hose set up a little challenging. I had to fit a custom neck down piece in behind that bracket. The Bronco radiator is a 2 inch set up and the 250 is a 2.5 inch. I don't think all 250 bracketry is like this. I think the early mustang and maverick set ups are a normal configuration with alternator on the passenger side.

Did the 250 just drop in? Yep. That part was really nice and easy. The 200 and 250 engine blocks are the same length. So transfer and tranny fitment was spot on. The motor looks a little longer due to the bigger and longer water pump on the 250.

Hope that helps. I can wait to get this puppy back on the road! It all still moves slow. If only I didn't have a job, a wife, kids, 2 small businesses, a dog, etc.....then I could work on my 66 full time. :lol:

Frame off is the way to go.
I have a mini starter on mine that might help with header clearance but that is a little way down the road for me.
I actually have a set of acc brackets like yours that I bought somewhere but my 1970 250 has the traditional acc design.
A few guys on classicbroncos.com have asked questions about the 250 upgrade so I can tell them it is pretty much a bolt in. That direct mount conversion looks like a good job. Keep us posted.

I want to mention something based on issues I had and some private message questions people have sent me.

Regarding flywheel & bell housing choice...know what you are grabbing. In simplest terms, there seems to be essentially two sizings(vast generalization as there is a little more detail beyond that). Some call it the big block bell housing vs. small block bell housing. That isn't a great description as you can find the two different sizes on small blocks.

Key questions to ask yourself:
Are you going to do 157T or 164T on the flywheel?
Is your bell housing designed for 157T or 164T?
What clutch fork and clutch linkage will you use?
Mechanical vs. Hydro? The Bronco is a mechanical clutch, so a hydro would be some extra fab and customer work
Do you have the right starter set up for what you've selected?

157T and the associated bell housings are found in the V8 Mustangs and other car applications.
164T and the associated bell housings are found in truck applications and some bigger engines in cars.

Keep in mind with the 250, you need a zero balance flywheel.

157T Zero balance flywheels--I could only find these via Ford racing. Maybe there are others places, but I didn't find a vehicle application for it.

164T Zero Balance Flywheels are used behind the 300 straight sizes in the F150's(also the 240 sold in the 70's). These flywheels are cheap and easy to buy at NAPA and other auto parts stores.

People have asked me--which one should I get? It depends! I'd say I think the simplest is the 164T set up from a V8 and keeping the mechanical clutch and linkage.

I hope this helps and if others have more info, let me know and I can update.

Here's a couple pages that helps:

More good information to have and should be very helpful for those thinking about the 250 for their Bronco. I stumbled across a 250 fw on ebay when I installed mine, did a search for ford 250 fly wheel I believe. The advantage with the 300 setup is larger clutch and easier to find. Often wondered if I should have gone that route.

Thanks! I am still having fun on the project and I am enjoying how it is turning out. I am doing the final steps to test fire the motor. I've got a short list after that to declare it done. Soon........OK, by summer.

That header looks really good. Do you think that you will have issues with fram clearance? If not I'll pull the trigger and buy one myself.

Frame/Body Clearance for the header is a challenge. I will be able to tell you more after I get the exhaust fab'd. We already adjusted the direction of one of the header collectors to give us a better angle. It will be a tight fit.

Yeah, I guess I didn't speak much on the rebuild. It has a mild cam (264/264 I think). The compression was bumped up as well. I am hoping those changes along with the Weber 38/38 and header/exhaust make it a fun drive.

Nothing special to that color. It was a generic dark silver in engine paints available at my local auto store. Many of my accent colors are dark grey/silver, so it seem to fit. I don't think it is a Ford color, but neither is the exterior paint.

Thanks! It is funny how far I've moved off the original idea. At the start of this project, it wasn't going to be a purty truck. I just wanted a strong usable runner. I've moved way off that goal. I will like the outcome, but I let the scope creep away on me. Good thing the wife has been supportive.

Getting close to the final under hood configuration. The custom intake needs to be polished or finished in some way. I've got a few other things to address as well.

Very well done. That is going to be a blast to drive and will get lots of attention. Looking forward to hearing feedback on how it goes with that built 250 it should have a bunch of low end torque.

I am excited too. I hope to be test driving later this week or this weekend. As we are tuning and shaking out in runs in the shop, the motor feels strong. I think the header into two longer pipes into one will help draw out some of the torque.

I'll get more pics of the exhaust as we get it out of the garage.

Well, It has been together for a while and I've been driving. I am really happy with the motor set up. Lots of torque!

Weber carb tuning is a dark art. I've got it pretty good, but need to do a little more tuning.

Do you have any videos of it running? How do you like the gearing paired with the tire size?

Tires size and gearing worked out great. I had used one of those tire size and gearing RPM calculators before I bought them. I have very nice acceleration and on the highway, the RPMs aren't bad.

What headers are you using? That is the classic inlines header. It is a nicely built piece, but...
Try the ‘stang ‘80s, ‘90s (v6) starter? I will. Smaller – like the expensive “minis”.

Key questions to ask yourself:
Mechanical vs. Hydro? The Bronco is a mechanical clutch, so a hydro would be some extra fab and customer work.

I will use the NV3550 so the Q is answered w/in itself.
ZF would B nice/easy by placing a Ranger hydro clutch (slave'n it's line) in the bell.
Got a '77 C4 from a bronk prts vehicle. May use it if daughter wants the rig (she's 19 y/o now…never drove a stick).

That's sweet! I'm enjoying mine, which has a 200 with the same head mods as you did, although I opted for a 2100 Autolite carburetor. I like your air cleaner setup, gotta do something like that for mine.
That setup along with 4.11 gears and stock 15 inch rims (that's about what, 26 inch tires?) got me 16 mpg today. Pretty pleased with that. This weekend's its first camping trip.

Yep, that is an Astrovan booster. No big logic to that one. They seem to be the most used one for custom systems. I think you could use any model you could find. I found the Astrovan one cheap.

The pump and double belt is the stock set up that came with my motor. I don't think it really needs a double belt.

The hydro boost works very well. I am not tied to motor vacuum, which is great. Especially with this lumpy cam.
