RE: [Chrysler300] Value of correct date block





It would appear that we are talking about two different dates.  One is molded onto the block when the engine is cast, the other is stamped onto a flat boss by the distributor when the engine is assembled.  The assembly stamp would contain other information such as the brand and model of the car, whether it is high-performance and any issues such as oversize/undersize dimensions—as listed at:  http://www.moparts.org/Tech/Archive/motor/36.html      The stamped information should certainly lag the casting date and is what identifies an original 300 engine.  And, the engine assembly date should be earlier than the chassis assembly date.

 

Now, I’m curious as to whether the IBM build cards or any other document have the original stamped engine ID date handwritten on them?

I don't know about the blocks specifically, but many castings have date codes built into the casting - frequently a month and year tag placed in the side of the "mold" before they are cast. Some go so far as to have a day and a shift code indicating which shift made it. I'm assuming it was for quality control in case there were problems to allow rejection of a group of parts cast using the same materials and parameters. These are generally raised letters / numbers on casting.

I meant that I don't think that there was any casting dates on 1960 Mopars plus I'm sure that there's a lot of engine blocks out there that were restamped when the engine was rebuilt.  Fern

Correct me if I'm wrong but I do think that there were any casting dates in 1960 mopars.

Personally I would prefer to have a correct block, but correct would mean a reasonably correct casting date - one that is sufficiently earlier than car's build date. And having gone thru that on another project, it may take quite an effort to find such a block. Having a P41 block with an incorrect date code would probably not be worth my effort compared to just rebuilding what you have.

Hello All--Thanks to the excellent information offered here, I've determined the block in our 300 F appears to be from 1964 (V41 HP).  As nearly as we can tell, at some point prior to our owning the car, a short block was put in.  It appears that everything else (ram induction, carbs, heads, etc.) are proper and presumably original to the car.

 

The engine is out of the car, and we are undertaking a complete re-build of it.  My question is, does anyone have an opinion as to whether we should stick with the 1964 block we have, or try to find a 1960 P41 block, which of course would still not be original to the car but would be mostly correct from a date standpoint?  Does that add significant value (enough to make it worth it to go through the expense and trouble of finding a '60 block)?

 

For a point of reference, we are doing a complete, sub-frame off restoration.  While we're not necessarily trying for a concours job, especially with detailed correctness in things like wires, labels, batteries, etc., it will be a very high quality restoration, perhaps one step down from concours (at least, that's what we hope to end up with).  The car itself is a black/tan convertible with factory air, and all of the options appear to be correct according to the build sheet if that helps.

 

I would welcome anyone's opinion on this subject.
