Smile 1955 Differential Replacement

Hello everyone - I have a 1955 Buick Century and a problem with it. Unfortunately for me, I'm upsidedown in having restored it without doing a thorough enough job checking out the engine and transmission before I started (oops!). Consequently the car is complete and pretty much as new now, but old 322 nailhead and dynaflo are tired (110 vs 170 psi factory compression, bad reverse selector) and leaking lots of fluids.

To make a reliable cruiser I think I should change out the drive train using updated Chevy componants (since I already have a free 350 transmission).

Because the '55 uses a closed drive shaft, I expect I shall also need to change the third member to accommodate the new Chevy 350 engine- turbo 350 transmission.

I would very much appreciate it if anyone out there could give me a place to start to determine a suitable rear end to choose for this application. I guess a tape measure would be in order right?! A couple of people I've seen on the internet have used a '79 Lincoln and '69 Chevelle rear end respectively, but can anyone offer other suggestions? BTW, I'd really like to have disc brakes too.

Thanks very much in advance for any assistance...

A 55 Buick is a big and heavy car. I would suggest finding a later model Buick (like a 1965 or so) with a 425 or a 401..... and a Turbo 400 transmission. Use them instead of the little Chevrolet.


A Chevelle or Lincoln rear end will have the wrong wheel pattern (different from whats on it now) and you would need two spare tires. The rear from the 65 or so would be a open drive shaft, the correct gear ratio, correct wheel pattern and possible correct width. Narrowing a rear end is also not very expensive.

Thanks for the suggestions Deuce, I will print and save them. Some of the ideas you've mentioned seem like they will save me some significant headaches. I've already had enough of them by starting with the wrong quality level car to "restore".

On the other hand it will make a great cruiser. We have a Buick wrecking yard here in Phoenix that I will check out accordingly.

Thanks again...jsc

P.S. Those cars of yours are beauties!
