Quote from: Michael Petti on December 17, 2021, 07:35:49 AMIf you are just interested in getting it running, a flat head is not that different from what you have worked on. The principles are all the same. Gas, spark, choke etc. If you want to go further, I'd suggest looking for a shop manual for it. I have seen some on the internet but not sure about your year.
Quote from: Tom Boehm on December 17, 2021, 09:28:51 AMHello KB, yes a 1940 Lasalle is a positive ground battery hookup. In 1940, Lasalles were either a 50 series or a 52 series. For now, it doesn't matter because the engine and mechanicals were the same. The 6 volt starting system will work fine but all the connections have to be clean. The battery clamps and poles, the positive battery cable connection to the frame, the negative battery cable connection to the starter, and the ground strap connections between the frame and the engine block on the passenger side all need to be cleaned of paint, rust, and corrosion. This will help the starter to turn faster and start easier. Even cleaning the rust and paint from between the starter and the bell housing will help. This is a first step. There is a lot of knowledge of Cadillac flatheads and Lasalles on this forum. Just ask. How long has this car been sitting? ps If the battery cable from the negative battery post to the starter is missing, buy the thickest cable you can find.

If you look at the body tag under the hood it will tell you the series and the model. A quick identifier is the 50 series has a beltline molding that runs the length of the car and round taillights, the 52 series doesn't use that molding. I've attached a couple of photos to help. I hope the owner's of these cars don't mind my using the photos.There's lot's of info here and on the web for these cars.As already mentioned these are 6v positive ground. The starter looks pretty much the same as any other except the solenoid is somewhat different on compared to later designs. One thing these 6v cars have in common is they require really good, clean ground & power cable connections. As well as cables big enough to carry the amps needed, 00 size cables, like welding cables are common, stay away from 12v size cables, they won't do the job. Depending on how long this car has been sitting you may find the usual age related problems of rusty gas tanks, deteriorated rubber hoses, bad fuel pump diaphragm, gunk in the carb, and on and on and on...Good luck and don't hesitate to use this forum for help.And we love to see picturesWes in VT
