170 out..250 in...

Post #1 by Jebus » Tue Nov 21, 2006 11:37 pm

Greetings All!
I have a cherry 68 half cab (less than 40,000 miles). I just aquired a 69 maverick 250 to replace the 170. I have researched alot of the swap items. The most daunting is the oil pan conversion, (or hack!). Is there anyone who makes an oil pan with rear sump for the wider 250 pan rails. I am a gearhead by trade, so cutting and melding the 170 to the 250 is not beyond my skills, but a ready made solution would be more desirable.

I'm second owner and it is a virgin. never been off road. It was a aluminum mill water pumper rig all of its life. In fact it had never left the mill till I aquired it. Took it home, cleaned it up, charged the battery, new 31's, new brakes, and now it is a daily driver. Drives as good as they get. Next is the paint after mechanicals.

I'll throw a couple of pics of the rig as I found it as soon as I get them uploaded to a server (looks like this site doesn't do uploads to board, what a pain!).

Cool!
I'm diggin' the throttle controls and tach? in the grill! :D You gotta keep those on there!

I don't think you're going to have any luck finding anything in terms of oil pans. You'll have to do the junk yard searching thing and hope to get lucky.

Will a pan off a later 200 fit on the 250? Rear-sump right?
They come up on ebay, I just posted a link to one that probably just ended:

No sir, they will not interchange. You will have to hack at the original pan of the 250.
But, just to let you know I just drooled all over my keyboard from your pics...God I love early broncos!

Oil Pan

Post #5 by Broncitis » Sat Nov 25, 2006 9:53 pm

I don't think you will find the oil pan you seek, also without a body lift you may come darn close with larger bell housing, the area between fan and radiator will be closer, but I think there is plenty of room, but the approximate 2inch rear facing brackets for radiator can be easily modified if need be. Also I'm not familiar enough with the 69 250, but almost all the headers are made for high mount starters in this application, although I think clifford includes the 250 in its EB header selection. Good luck, I will be curious how you fare, at least you will be able to run a decent clutch, the hood also seems to fit pretty tight over the 170, although I never measured. A small body lift is very valuable for room though and also tucking a 23 gallon gas tank up in there a little higher assuming you have the single 12 gallon tank MIKE

OIL PAN

Post #6 by Broncitis » Sun Dec 17, 2006 8:03 pm

I will be very interested in what your final conclusion is on what will work best for an oil pan if you use the 250 in your EB. I can't find an over the counter solution, any help would be great. Mike

Considering Selling "sigh"

Post #7 by Jebus » Wed Dec 20, 2006 1:10 am

Sadly, I'm considering selling the whole project. Time is at a premium with my work and I might be taking on more. With the rarity of an early half cab and the low miles of this classic vehicle, I have been entertaining many offers. I would really like it to go to someone who will not chop it up or off road it. It has never seen mud, I have the complete history of the vehicle. I am the second owner. It spent its whole life on asphalt at a mill. I sure hate to do this, but I just might for the right offer.

Wow, these R old posts, OH well. I'll try:
U may have had a Carter carb on that 170. I do. Need a dash pot (for the choke). It closes the choke after warming up...
Wouldn"t wanna sell/ship it?

BTW: to put the 250 in, just put the pan on backwards. It fits around the D30 or 44 or whatever U got in the frnt end. Fella in VT did that. Ask me more to get the details...

Yep, real old posts.
Just in the last couple days I remember someone on classicbroncos.com removing or planning to remove a 170 from his bronco. May want to check there. Are you sure about turning the pan around? I would have to check again but the 250 I put in my Bronco did not look like that would work. I have adequate clearance on mine with a 2.5" suspension lift for the type of driving I do.

Excellent, a reply back AND some useful info 2! Thanks so much.
Hey, listen. A guy (from VT I believe) on the site I used 2 use, B 4 my crash (E. Coast B. Registry, I think) posted quite a bit. Most had 302/5.0/351 in mudders n crawlers. Mine is not that variety so I listened up when he posted. He claimed to put the 250 in w/a BODY only lift. Put the pan on backwards, may have welded the 170 1/2 to the 250 1/2. I can't remember. It seems to B a moot point due to you being present and doing the swap-in successfuly. If U have interest/X I'd like to ask about it.
I'm in Amherst, MA where everything goes to the crusher that's more than 10 yrs old. I gotta find a doner for the 250. Number 1 problem: I have yrs of production and models that had 250s but the list is not matched so it's very difficult to sort it all out. Number 2: I'm not totally sure it's what I need (the 300 IS too much). May B I'll just leave it @ that to see your responce to Q on if U have X/interest for me..

I did read a post on classicbroncos.com on matching two oil pan halves from a 170 and 250, requires welding. I will probably do this someday. Also I put a 1" body lift on mine to make the nv3550 install easier.
The 250 engines were available in some Maverick, Granada, Mustang and possibly other models. It pretty much requires a trans change as the 250 has the small block Ford bell housing pattern. I know some have put the 300 in a early Bronco but it looks like a lot of work to me. If you are not too concerned with staying original a 200 from certain year vehicles are a bolt in operation with instant performance gain. Not alot but some.
I will try to answer any questions you have.

answer any questions you have

Well I keep reading your signature and wanting to go almost in that entire direction. After puttin around since '82 I'm ready for some changes. Just rebuilt the carter YF w/help from the ford-truck (FTE) forum and seems like a new rig!!! No money (unemployed) so THAT was afordable. From what little I know the ZF may be for me. Body lift, Bilstiens, 250 (for $600, but down in TN me in MA :cry: ) all the clifford stuff, some ignition upgrade. Nice to dream...The '77 frame and accoudermints (2" SL, D44, PS) this summer helped. Ring n pinion to match the 33". I'd be done (ie in the poor house, but happy :lol: ).
May be @ our next contact I'll take U up on your help offer n tell U my need, pick your brain about if the above dreams 'ill 'get me there'? I think you're in NV and that could mean you have some insights not available to me!
Again, thanks for your contacts/offer/presence.
Chad

what the heck, I got the D5DE instead. :roll: Same state ( TN - right end not left) different guy. Step 2 :arrow: is the steam clean. Now I need a bell n starter to listen/ck compression on the stand. 4.9/300 I6, 5.0/302, 351/5.8, any other bells fit. What would the vehicles B? What yrs? Same ol' prob., all crushed around here n don't know "who had what" but know what I need.

Some 1 said my 4.1L's fly wheel, bein so thin (1/2" or less), is auto n I could get either auto or manual transmission bell. Don't sound right? I'd like to get a mani so it'll slide in where my 2.8 was, said it'd bolt right up. Guess I can put the fly wheel from the 2.8 to it? If I got a bell w/hydrolic do you think it'd spin a ZF if I snuck it in behind (one for $300 from neighbor)? May B a 5.0 bell from one of the ford p/u or SUV's had a donner (4 this) w/a hydrolic clutch to fit in the ZF - bad idea?. What else is needed beside slave n master for that - change the clutch, throw out, pilot, bronk's peddle? May B a different cross member 4 the ZF?

Most expensive is to put my C4 to it (needs rebuild). That's nother Q. Bronk is a work truck, need low rev grunt. Auto w/OD may not fit the bill (w/a 250), No high revs allowed, hmmm wonder bout that with the C4, may B manual throtle body.

2" suspen. lift I got = no pan probs, still need the 1" BL? Option: graft the 170 to the 250 pans, redirect the p/u tube to (is it) rear or frnt sump for the 4.1 conversion? Looks like it's in the middle as stock.

Wow, lotta Qs. Long way 2 go, unemployed. Wish me luck...

Hey Chad did you ever do the 250/3550 install?

If the OP sold the halfcab I'm guessing he no longer frequents this site?

my 170 out...a 250 in...

Post #16 by chad » Thu Mar 02, 2017 6:57 am

Well Jeff, things R progressing v e r y slowly.

Got a coupla motors (long story - 1 frm VA one frm TN, two long term on-line buddies [10 yr.s each] for 150$ shippin, 150$ each). One has been machined and partially assembled. I'm hand fitting the exh. port divider in the '69 250 ('stang) right now. I cleaned the rockers but need to get the end plugs for the r. shaft back in. Uncertain on the prt #s.

Got an NV 3550 and just need 100$ more for the adaptors (will take one month more for final savings - that's a wk's pay!). Almost all parts R here'n assembled, just need to place on the rig. Last of the logs have been hauled up to the neighbor's band saw mill. After 30 some yrs the bronk's final season is about here (late March early April - no more trees to drop, the baby forest animals will be nesting there & don't wanna kill any). Hopin to switch from 70% off / 30% on rd to the opposite…

Thanks for askin~

Re: 170 out..250 in...3.03 out NV3550 in

Post #17 by chad » Wed Oct 11, 2017 8:37 am

well, 170's pulled.
Time 2 power wash the bay'n scratch, wipe'n paint the bay (& 'under' hood)..

The NV bell's gone & the AA adapter'n ford sb bell is mounted.

I don't look forward to swappin out the spud shaft on the D20. Gotta glue the numerous roller bearings in (w/heavy grease) the housing while swapin the transfer's output shaft to the AA one.

This aint like the 34 yrs of simple maintenance I been doin
8^0 yikes

BTW:
Wanna buy a strong 170? a 3.03? (some ada local circle track guys use this 3 speed - good to 500HP, due to lightness)
