Plym 46 i dont think you will find a catalogue for a rebuild ,who can tell when these engines were rebuilt in the past using the original block (ie)reboring to take 10, 20 30 thou or more over size pistons , or 10,20 thou undersize bearings. i would have thought the first thing you did was pull the engine down to find out what was needed befor ordering parts, they are after all 50,60 years or more old and most of them have probably have been worked on in the past , i,ll rephrase that its almost sure that most of them have

222? Interesting -- I don't find any 222 listed as a replacement engine. There is a 232 which was a 230 cid engine. 220 was the replacement code for a 218.

Now if only we knew what that meant. My original engine said to order parts for a Mopar model B rebuild. But when it was pulled down everything was standard except the rear main which was .010 undersized. Wonder if there is any catalog for these official rebuilds. then of course there were the jasper's and the sears and rhoebuck, and the western auto, a a slew of others in the after market as well.

Yessss, there is a tag under the distributor and it says" Mopar #222 replacement "

If there is no number in the normal place, check the casting date on the left side of the engine.....close to the starter. Chrysler sold new, replacement "short blocks" (minus head, etc) after the war. Its my understanding some federal law prohibited the use of engine numbers or re-stamping of the original number onto these replacements. I doubt very much anyone "ground off" the serial number. A casting date later than 1936 would indicate a replacement engine that was new from the factory. The riveted brass tags usually had a model number on them (such as Model 19) but as noted, these tags were easily broken off.....

look in the area on the block in behind whee the vacuum advance and wire loom are and check to see if thee is a metal tag riveted to the block or a rivet in the block with the tag missing. A lot of rebuilders like japser, and mopar licsensed shops attached a metal tag specifying rebuild specs and measurments in the tag along with the rebuilders umber on it. Tags were thin brass and maytimes over the ensuing years would have been knocked off.

Chrysler did sell bare blocks with no numbers to lots of rebuilders int he 30's-50's.

And this situation, as prevelent as it was carries a lot of weight toward opening up POC judging for accruing points for the engine during club judging. After all other than that number it still is a Mopar Flathead 6.

The flat spot on the engine right here.

For 1936 the engine number should start with P2 regardless of whether the car is a P1 or P2.

The engine number should be front left of the block (above the generator). Sounds like that is where you are looking.

I've heard that remanufactured engines sometimes had the engine number ground off. Also that replacement engines were shipped from Chrysler with no number stamped on it.

Hello again! IN the book it says the engine number should be on "left front side of block".And this number should start with a P1-1000 or P2-1000. I cannot find this number.There is a raised surface towards the front on the left side but nothing is stamped on it. Is this where it should be?Thanks.
