A '55 nailhead into a '57 Buick - Can it be done?


Recommended Posts

Hello all,

I have a very "dilapidated" '55 Buick Century with a Nailhead and was considering imstalling it in a '57 Buick. Is this a reasonable easy job or are the '55s and '57 too different for this fit?

Thanks in advance.

Ralph, I am not a 55 specialist, but I suspect that there will be major differences in the way the engine fits in the compartment as well as how the linkages will hook up. The 57 was about 3-4" lower in height than the 55 /56 and some of that came out of the engine compartment, based upon the different air cleaners between the two model years. I think the 364 is an all new engine for the 57 model and carried over to at least 1961, maybe later.

I defer to OldTank on this one as he is the 55 engine guru, but as for the 57...great car! Does it have an engine in it?

There are different splines on the shaft(propeller" between 1955 and 1957.As someone in the forum sad, if fix one problem you will have three new problem and I think that will happend in that case.

Greetings 57BuickJim and Lief in Sweden. :)

Thank you kindly for shedding light on this subject. I am just beginning my learning curve regarding these beautiful cars (being busy previously with '65 Marlins and '66 Chargers)

So, I will not make this swap and to answer 57BuickJim's question, the '57 does have an engine in it and from what I was just told by the seller, it is re-buildable.

The '55 Century that I DO have at home is in really bad shape with lots and lots of body rot. I have a major challenge there. I am looking to buy the '57 if I deem it worth the asking price because I really love those rear quarter windows. It's a 2-dr post car though and it so far away from me. :-(

Thanks again for the replies.
