Ok, after 170k miles, engine seized up on me 4 days before christmas. Had plenty of oil, so no sure exact cause and didn't want to pay the labor charge to rip it apart. ( I can work my way around under the hood, but i'm no mechanic and don't pretend to be )

I was gonna have it rebuilt, still might sometime, but with the $1700 cost is a little outta range at the moment. Might do it myself someday.

Found a 250 with 13k original miles on it, and curious what, besides the oilpan would i have to replace for cost purposes.

btw, original is 69 mustang coupe, 200ci.

Thanks in advance for the help :)
 
When I swapped the 200 for a 250 in the Maverick, the motor mounts were different, the exhaust would not hook-up, due to the taller motor, your trans will not bolt up, it would be easier to find another 200...

That statement means you are not allowed to think further about doing a 200 to 250 swap. I have a 69 250 from a Mustang sitting in my garage and after researching the idea of a 170 to 250 swap, it'll sit there for alot longer. At least until I toss out everything but the head, dizzy, carb, & maybe exhaust manifold, maybe. Now on the other hand, how about a V8 to 250 swap. That might be easy.

not allowed? ;)

If i'm not mistaken, the C4 auto transmission should fit both. The 200 was a T code, so it had the later bellhousing attachment. Or am I wrong?

I wish it were that easy to find another 200... 1k newly rebuilt from rebuilt-autoengines.com with 7 year warranty, or $200 for the 250.

I haven't had a chance to see everything included with the 250 yet, hell, could prolly rip the exhaust and oil pan from it too.

Possible things I'd need -

1) Transmission adaptor or transmission
2) Oil pan
3) Exhaust pipes, etc..
4) Motor mounts
5) ??

Anything else Anyone can think of so i can check to see what else my friend has layin around?

If Heads fit both 200/250, same go for Intake/Exhaust Manifolds?
Just trying to price out which is gonna be more cost effective in the long run.

Thanks again.
 
everything after the block on a 250 is the saem as a SBF...flywheel starter, tranny. adn the block is taller meaning new exhaust and motor mounts. I say find another 200 and drop it in. then rebuild your own at your own pace. it really isn't hard and if you do it one step at a time it will help to soften the blow of cost.

Howdy NJPony69:

Happy New Year.

I'm going to add to your dilemma by saying that the 250 would make a nice upgrade in your '69 Mustang coupe. What did the 250 come from?

The 250 pan may/should work. Anyway, the 200 - 250 pans are not interchangeable. Neither are the transmissions. The 250 uses SB V8 stuff- same bell and trans mount. Know that the radiator inlet and outlet are 1 1/2" on the 250. 1 1/4" on the 200. Water pumps are not interchangeable.

Since the '69 Mustang came with the 250 as an option I'm thinkin' that you would not have problems with fan to firewall clearance. Other considerations would be motor mounts, trans and trans mounts. If you could find the original motor mounts that the 250 used you'd have that solved. Other wise look for a Maverick or a Comet as a source.

50 additional cubic inches in a vehicle as big as a 69 Mustang Coupe would be more than worth while- and, I think, cheaper than a 200 rebuild..

That's my two cents, for want it's worth.

Adios, David
 
Due to my work schedule, a friend (who does most the work that I'm unsure of or just don't have time to do) found the 250.

He located a 2nd 250 today, but still waiting for a phone call back to find out more details. He checked it out and it was running, so depending on what they're asking, I could probably rip the engine, tranny, mounts, etc.. right out of this one.....I hope.

Its funny that the 250 needs so much more, when a 302 is a straight bolt-in with swapping just Headers, Mounts, Pulleys, Bellhousing & Radiator.

Besides Trans mount, what else is different between the tranny's? Even with the 250 option on the 69, the C4 was the trans installed.

I'll also find out what the 250 is coming from today.... Hoping its from an earlier model, so it has the Higher CR.

Thanks for all the feedback, Much appreciated :)

Happy New year!!
 
What is all this nonsense? I just installed a 250 into a '65 Falcon today with very little problems at all.

I used the Granada motor mounts on the original 170 brackets. Used the 250 oil pan. I have a Cliffy dual outlet header and am using a 3.8 starter. The motor sits higher. I am using a large bell C4 from a '70 Mustang. And this is all going into a car that used to have a manual tranny.
 
Howdy Again NJPony69:

Sorry! I didn't mean to mislead you. Installing a 250 into a '69 Coupe would certainly be less involve than swapping in a V8. If youget into the details of a V8 swap, you'll find that it's not as simple as some make it sound.

Keep us posted on your progress.

Adios, David
 
Yes! The swap IS easy, IF you have all the parts! But, if you need motor mounts, or exhaust pipe won't reach, bell housings, starters, it may be more of a pain....I have put a 250 where a 200 was, I have swapped several 302's where a 200 was, and even put a 460 in my 69 Mustang. But, if you are "challenged" or have to drive the car the next day, it may be more of a swap. We are not trying to talk you out of it, but I got stuck at the shop well into the night due to not having a second ride home, cause the exhaust would not reach, and a few other problems, this was a long time ago, since then, I have a welder, and other tools that would make this easier.
 
Naaa, my friend does all the work in his garage. We can get all the parts, so getting isn't the problem :) I was just wondering what exactly I'd need to replace so i could cost it up. I'm sure he knows everything involved, but he just had a death in family last night, so wasn't able to really talk to him today, and wanted to know more for myself just to know.

The car we're pullin motor from we can pull the mounts and oil pan from without problems, possibly bell housing. Starter I can get at Pep boys as a last resort if necessary....they know me there well :) If exhaust pipe won't reach, well perfect excuse to upgrade to headers, and maybe just a whole new pipe and muffler altogether...

And no, Its not needed the next day :) I always have alternate transportation to work available.

Again, thanks for the help, hints and insight. Difference between the first few and last posts kept my hope alive hehe. I'll definately keep you all up to date on how things are turning out.
 
btw, I have 2 engines I can go with...

Found one complete, with complete car, so I can pull engine, mounts, bell housing and torque converter all out of this one ( and starter and miscellaneous stuff)... 300$ for the engine, just need to price other stuff...
60k on engine...they're not sure if it was rolled over, so possibly 160k... know for sure this is running strong....its coming out of a grenada.

2nd is a 250 in Englishtown, they say its 1350 original...yes, 1 thousand fifty lol. I gotta see what kinda shape its in and if its complete or not. Prolly take a ride out this weekend. $200 for this one...

Thanks for that link Mustangsix... Its a great help.

Got old engine already out of body, so might actually have it running by end of weekend, weather permitting. Prolly just need to get a muffler shop to weld me a special pipe to fit around starter, or just buy a new pipe. I'll post details for yas on how it works out :)

$1700??? When the engine blew in my 81 Granada, I was quoted $500 to drop a new (used) motor in.
 
Machine shop wanted $1700 to totally rebuild the 200... Maybe its just NJ....Cost of living here is like the 2nd highest in the Country next to Cali.

$300 for the complete used sounds so much better. Prolly 400 complete with everything else i need to pull off the old car.
 
Make sure you get the proper radiator & fan. And if you do the swap, don't slam the hood until you check it won't hit the aircleaner.

I'm sure putting a 250 into a 69 mustang will be easier than into my roundbody Falcon. But it still must require a fairly long list of different parts needed. If indeed you don't need a new transmission, then maybe it is not too big of a job. I think that you will at least need the bellhousing and unbalanced torque converter for a 250, if not the whole tranny & driveshaft and then the linkage. In my 61 Falcon, I'd have to strip the whole under carriage and engine compartment. Not to mention a hood scoop or lower profile aircleaner followed by customizing the motor mounts and radiator type & location & fan & linkages & hammer the firewall & tranny tunnel to fit it.

And that is where my earlier doubt came from.
