1940 LaSalle Question

Recommended Posts

Hi all - new to this section of the forum with a quick question for the experts. Is the 130 HP LaSalle V-8 the same powerplant used in contemporary Cadillac models, perhaps the 60 Special? Understand this to be a good engine for the era?

Will be looking at one of these in next week or so and have heard these are pretty good road cars - at least that is what I understand of the Caddys of that era.

I know what to look for in general terms having owned several cars of this era, but any specifics would be helpful as well.

Thanks in advance,

The 37-40 LaSalle is a 322 cu in to the Cadillac 346 cu in, which for Cadillac was introduced in 1936. The difference between the LS and Cadillac being 1/8" bore difference. They look identical and totally parts scramble between each other. They are good road cars, I have owned a number of them over the last 44 years. Currently a 37 Cadillac coupe and a 39 Lasalle convertible sedan.

The 346 version was used in light tanks ( two engines and two automatic transmissions) and other applications in WWII.

Call me or PM if you have any specific questions. Jim 43 Grantham, NH 603 863 2621

Adding my unsolicited comments: Egge in Los Angeles has a full complement of engine internals for these flathead V8s. If you did buy one and have the engine overhauled, chances are it now has Cadillac pistons due to a slight boring-out of the cylinders, along with modern materials of construction in the valves / seats that will permit use of unleaded fuel straight form the pump.

Hope you found a Cad or La Salle to your liking.
