Marty, thanks for confirming what I was beginning to suspect about the 35P manifolds - their individual 6-digit part nos. are -NOT- included in the parts list bec the factory sold manis only in pairs. As to the 6-digit part no. cast into the tranny case on my current project not appearing in the parts list ... I have other 35P cars with tranny-case nos. that do appear. Therefore, I suspect one of two things about the 631841 tranny in my current 1935 Ply project: 1) it is an original 35P part that, for whatever reason, didn't appear in the factory parts list, or 2) someone replaced the orig. tranny with a similar unit from a Chrysler or DeSoto. (The no. isn't in the 1934-36 Dodge car parts lists but I don't own comparable Chrysler or DeSoto parts lists.) I mainly want to make sure I have an original part before I go to the time and expense of restoring it. Thanks for your insight! Cheers, Curt

Bob, I can't help you directly but I can share that I've also been very curious about various other marks on the blocks of Chrysler-product flathead-6 engines. For instance, there are six thumbnail-size bosses cast high on the left side of each block, each one signifying the cylinder adjacent to it. The 1935 Plymouth engine I'm working on right now -- I don't have my notes with me at the moment -- has a single letter stamped in each boss: A, C, C, A, B, C, or something of that sort. Are these instructions to the assembly line workers? Also, following the six-digit head and block part nos. it's common to see a suffix such as "- 3." What does that code mean? All of my block and head castings have a stylized "NH" (I believe it is) cast into them. I've always thought it was the name of the foundry ... but now I'm unsure. There are also stampings in various places on the engine deck, hidden by the head and head gasket when the engine is assembled. For instance, someone stamped a "Z" in the head of my 35P engine. This is a code of some sort. Do you know what any of these mean? Thanks!

The 1935 Plymouth I'm working on has three parts I can't identify thru the factory parts list. One is the transmission, whose number, 631841, simply doesn't appear. I thought someone might have swapped transmissions with a Dodge but the number doesn't appear in the 1934-36 Dodge car parts lists. I'd like to check similar parts lists for Chrysler and DeSoto to determine where this part came from. Can any MoPar fans with these lists help me out? The other two mystery parts are the intake (601418) and exhaust (604501) manifolds. The problem here could be that, according to the 1935 Plymouth parts list, the factory sold manifolds only as a pair. So it's reasonable to assume that the part no. for the pair wouldn't match the number on either manifold. Does anyone know this to be true. A plea to other 1935 Plymouth owners: do the part nos. cast into your manifolds match those I've given above? One further thought: has anyone else encountered any part on a mid-1930s Chrysler product that does -NOT- appear in the parts list? Is it possible, nonetheless, that the car came from the factory with this part installed and that, for whatever reason, the number didn't get recorded in the parts list?
