Help with '68 C4 with '76 Inline 6

Post #1 by COJake » Sun Nov 06, 2016 5:59 pm

Hey Ford six Members, I have a few questions about a swap that I can't answer myself. So I have a 1968 mustang with the original inline 6 and a c4 auto transmission. I've had this car for years and it is definitely a tired engine, so I have been looking for another 6 to do an ‘easy’ swap without changing brakes/axle/driveline/… etc that a v8 requires. So I found a listing for a rebuilt 6 that was a steal and i bought it up, and I was told by the owner that it was out of a 1976 ford. I knew some details would be different, but the one big difference I noticed was the size of the rear of the engine where the bellhousing attaches.(a picture of the block with this is below, and disregard that the oil pan is off) It is noticeably different and I was wondering if it requires a different bell housing like that of a small block 302. The number on the OLD block reads “AL-C8DE-6015-B”(At least that's what I can read, a picture is below, tell me what you think it is if i'm wrong) and the new one is “1-EIBE-6015-BB’(Picture is also below). So if anyone could tell me what I can do to attach this engine to the original c4, and what bellhousing works, and anything else that I would have to know for this swap that would be appreciated. Thanks.
-Jacob

Hi Jacob, your engine isnt a 1976 its one of the late 200's with a low mount starter (1980 to 83) the block casting makes yours about a 1981 to 83 you need the casting date code to be exact. You can adapt a SBF V8 (6 bolt bell mid 1965 up) off a 289, 302, 351 car C4 trans to that block then it will also bolt to your C4 (see below link for info). You will need a different Flex plate and torque converter too. Or you can also hunt for a 1980 to 83 3.3L / 200 bell housing, flex plate, and torque converter out of a Ford Fairmont, Mustang, Mercury Capri (Fox chassis) etc. Good luck :nod:

Here is another recent post discussing finding a solution for missing parts on a late 200 low mount block has some good pictures too.

Even a bad day Drag Racing is still better than a good day at work!

Current project is a 1988 John Deere 420 Garden Tractor I need a few small parts to get it fixed, plus some cosmetic items, maybe a few attachments, if you happen to have or know of JD 420 parts would welcome the help!

Hi X2, also your carb mounting is bigger on the newer engine and your old carb won't work. The newer engine has the better head. Get the Ford Falcon Performance Handbook for all engine and tranny info. Good luck

Where are you located?

I have everything you need.... carb, bell housing, flexplate, torque converter, and hardware off of an '83 200.

Hi Bubba22349,
Thanks a ton for your reply! It really gives me some valuable insight into my project. I have a couple of questions regarding your info though. First, you suggested that I may find the trio of the 1980-1983 bell housing, flex plate, and torque converter. So will that still bolt to my c4 or will it have a different Bell-to-transmission bolt pattern, and will the torque converter still spline up to my existing c4. I hope so Because in that case It would require the least modification of parts by my hand, and more parts specifically for my engine.

Yes for the most part this is a bolt up and go deal if you find the right 1980 to 83 parts. They will bolt up to your new 200 engine block. The late bell housing should also bolt up to your current C4 case, the one other part you will need is a different input shaft to match the spline count of the new convertor.

This is were it gets a little difficult to ID them as there are three different input shafts yours now ishould be a 24 / 24 spline count (same for all the 1964 to 1969 year models. In 1970 they went to a 26 / 26 spline count, and in 1971 up they went to a 26 / 24 spline count this last one should be what you need to mate the new torque converter (is a 28 spline) together with your trans. This input shaft just slides out so its real easy to change. Test fit the new shaft goes into the late model new convertor on the one end and that the other end still fits into the front drum assembly of your trans (24 spline) Your starter might also need to be changed if so you could get a 1980-83 unit that would be a bolt on or if you plan a set of headers sometime in the later you could try adapting one of the smal high torque starters too. That should be about it to compleate your engine to trans swap, along with using the right engine oil pan and pickup tube off your current engine to bolt it into your car.

I have not tried this swap yet though was planing to on my project car if I can find the late big bell 200 block. There may be a few other small things to make it fit into an early model chassis like minor rewiring, vacuum and other hoses, maybe the exhaust head pipe might need to be modded to fit with this new C4 bell but that shouldn't be that big a deal for most good muffler shops with a tube bender or if you can weld you could remake yours fit too, good luck :nod:
