Guest jpm123 Posted March 21, 2014 Share Posted March 21, 2014 Does anyone know the correct firing order for a 1927 LaSalle 303. The cylinders are numbered (stamped on the heads) from front to back on the left (driver’s side) 1-4-6-3, and on the right (passenger’s side) 8-7-5-2). But I can’t find documentation for the correct firing order anywhere.Any help with this or any other helpful hints in setting up the distributor would be greatly appreciated.ThanksJohn Micciche Link to comment Share on other sites More sharing options...
MCHinson Posted March 21, 2014 Share Posted March 21, 2014 jpm123,I have moved your question to the Cadillac/LaSalle forum. Hopefully someone will be able to help you here. Link to comment Share on other sites More sharing options...
Johan Boltendal Posted March 21, 2014 Share Posted March 21, 2014 1L=4R=4L=2L=3R=3L=2R=1R in this sequence the driver side front cylinder is nr 1 the nrs on the head are the cylinder nrs used by Cadillac , as used in 1- 2- 3 -4 etc giving the firing order in that system 1 is 1L nr 2 is 4R nr 3 is 4L etc this info goes for the laSalle 340 but should be OK for the 303 as well.

Ivan Saxton Posted March 22, 2014 Share Posted March 22, 2014 The documentation of the firing order is very simple. It is stamped on the cylinder heads beside the spark plugs. (It is probably only about 50 years since I had to use this on the 1927 Cadillac that was my first road car.) Link to comment Share on other sites More sharing options...
