Identifying 603 Manufacturing Date Anyone?
I'd like to know when my 603 was produced to see if it was a replacement, does anyone know how to identify anything from a date wheel or serial number on the block?

Do you mean replacement as in not the original engine that came with the car or as in it was built as a crate engine?
A VMI or the EPC will tell you what engine serial number came with your car. I wish someone would hack the EPC to see what VIN originally hosted an engine serial number. Sixto 87 300D |

If its a 3.0L 603 it is either 86 or 87.

It's a 3.5L in a '91, with a #22 head.
I'd like to find out if the engine is also newer than the car. THe EPC might tell me if it's original, but not if the engine was replaced with a new vs a used or rebuilt. If it's significantly newer than the car I'm thinking it might have updated rods.

You can kinda deduce from the serial number. Look for a 95 S350 on eBay with VIN 27 or greater. Get the engine serial number for the VIN from EPC. If the serial number of the engine on the 91 is close to or greater than the eBay engine serial number, there's a good chance it has updated rods. Mind you it's a leap to say the serial number of a 603.970 follows the sequence of a 603.971, but it's a start. It's enough of a leap to believe 95 SDs with VIN 27 or greater have updated rods. I haven't seen credible documentation.

That sounds like a logical first step 62, thanks.
