Re: [Amc-list] an udder motor

Dating an engine without the proper code just can't really be done. I don't know if the engine was mis-stamped or it's a service replacement block. I can't find any sources that differ from what I have in the book, but engines with "odd" numbers/codes occasionally pop up. I wish I had a definitive answer. The serial number or day/build code would be on the intake side, front top corner of the block, right near the water pump and just below the block/head parting line. Maybe the light stamp is the problem -- the letter and one number didn't get stamped? I doubt that -- more likely a service replacement, or someone had one too many beers over at the "Brat Stop" for lunch and screwed up. 

The oil filter was optional through at least 62 -- prior to 63 the TSM engine photo doesn't show a filter (except in the 62 big car TSM), just the neatly bent line. The 56 OHV engine still had the side mounted water pump like the older L-heads. I don't know if the filter was ever standard on anything but the 65 196, but I've never seen a 63 or newer without one. Assuming the filter was standard starting in 63, you have a 57-63 engine. That's not much help, is it?!!

Numbers: Frank, I now have to engines with block casting numbers 
3160133. The machined pad on the drivers side (intake side) is stamped 
21208, light stamp. The left (distributor) side is stamped J22156 (heavy 
stamp), which doesn't appear right according to the Red White Blue book. 
Any ideas?

No oil filter. Line ran from the main gallery to the head with a nice 
neatly bent line. There's no oil outlet from the front cam bearing, so 
it's an older block?
