78 200ci and 83 200ci

[Bobs68]

Hey all, I have the opprotunity to buy two running 200's, one from a 78 Fairmont and the other from an 83 Zepher. Other than the oil pan is there anything else that will prevent either of these engines from fitting in a 68 Mustang.

If I'm correct I think they have the Fox body oil pan. Will one from the older 6's fit? Will I have to change the oil pump?

If the 83 has the low starter does that mean it has the V-8 bell housing pattern? If so is it a dual pattern that my manual transmission bell housing from my 68 with bolt up to or do I need to source a V-8 housing.

If I bought these they would just be backups to my motor. I will probably rebuild one of the short blocks but if and when I install it I will use the modified head from my Mustang, and remove all the smog related equipment.

Since I plan on installing a turbo on my, other than a cam and double roller timing chain, stock lower end I will probably end up needing a new motor sooner rather than later he he...

As always thanks for all the advice from the forum.
Bob

Howdy Bob:

The other obvious difference externally between the '78 and '83 200 and your '68 200 will be the front pulley and accessory drive system. The later engines are longer as a result of the change. The early, shorter water pump and pulley system can be interchanged on the later blocks.

In changing to the early style pan, you will need to use the '68 oil pump and pickup.

IIRC, the low mount starter bell will not be a direct bolt up to an earlier block.

Adios, David

Thanks David, sounds like the 83 will be doable, I just need to find a V-8 bell, I already have the 5 speed. Hey then I can do the cable clutch mod! I'll just have to explain to the wife why I need to modify my drive shaft again

Using carparts.com it looks like the Fairmonts and Zephers only came with C-3 and C-5 auto's and it doesn't show an 83 Mustang with a 3.3L. Will the manual v-8 bellhousing from a 5.0 bolt to this engine?

8) here is the procedure to adapt the 5.0 bell housing to the low mount starter 3.3l;

understand that this is ONLY for the low mount starter 3.3l.

In a Fox chassis Mustang you could get a 200 / 3.3L have seen them though don't think many were made that had a stick trans after 80.

1979 3.3L 1V 6cyl 85hp Code T
1980 3.3L 1V 6cyl 91hp(MT), 94hp(AT) Code B
1981 3.3L 1V 6cyl 94hp code B
1982 3.3L 1V 6cyl 94hp code B

28th down.

See http://mustangattitude.com/mustang/engine_allci.shtml


In 1982, the B-code was optional 3.3L 87hp 6-cyl, and it was the manual and auto one. Between 1980 and 1983, either low and or high mount type was available, under the same engine code. California still had a four speed wide ratio listed on the Capri RS anyway.

There was a reported RS version with 97.5 hp, and it was manual with a 3.08:1 diff with 0.81 overdriven top or auto and 2.73. But the code has never been made public, and there is an issue of Car and Driver which lists the carb as "Holley W".

Ford did some crazy stuff with B-codes that definately had an SROD manual gearbox option after October 1980 in the Mercury Capri and Ford Mustang, but no-one knows if its a blue ( high mount starter) or grey (low mount starter) engine. The engine decal was different for each color engine, but the engine was still a B-code. It changed letters from T to B code with the 1981 VIN number

Was Linc running his stock C5 in his turbocharged Mustang? I know it was a fox body. I can't find anyone that claims to have a manual bell housing for the 83 motor.

Maybe I should just get the 78. They both run well and seem to be in pretty good shape. I may get both just to have the parts.

Lincs 200 had a 1984 Ford Fairmont low mount engine and he used it in a 1983 Mustang which had the 3.8 C5 gearbox.

As for California, emmissions regs may have killed the standard manual 3.3's. My 82 is high mount block, and I don't know why either, but its a compliant CA model. Weirdness reigns suppreme with I6 Fox bodies.

Why the 6.75" diff when there was a standard 7.5" inthe Fairmont, why the low mount when the auto still had high mount, where is the code for the Holley W 97.5 hp engine, and what is the engine decal for a manual B code Mustang.Questions, questions, questions

With the late 200 (1980 and up) low mount block it's not hard to adapt an SBF V8 stick or auto bell.

Alright I've read the article that rbohm posted a link too and it seems straight forward.

I think I will get the 83 motor and plan on adapting a 5.0 bell and cable clutch set-up. I'm sure my wife will understand having to modify the driveshaft again. :roll:

That would be a pretty nice set-up.

Thanks for all the information guys.

maybe with the right presentation

 

[Bobs68]

Well I would be making it an inch longer......

Bob,

The hard part isn't the bellhousing, it's finding a flywheel for that combo. The 200 crank flange is a different pattern than the V8 so you will have to have a 157 or 164 tooth flywheel redrilled and rebalanced.

 

[Bobs68]

Thanks for that info MustangSix. So the 9" manual flywheel I'm currently using in my 68 block won't work?

8) not with the low mount bell housing.

Too small.

A 5.0 bell uses a 157 tooth wheel and either a 10" or 10.5" clutch. I'm not quite sure the center crank register is the same either. If it is, that makes it easier, but otherwise some sort of adapter needs to be fabbed up to center the flywheel on the crank.

Make sure you get the block plate that matches the bellhousing, too. That indexes the starter to the bell.
