PO#s vs. Serial #s

[Shawn Newcomb]

Barry's PO# 137 Barry's VIN: 1126

My PO# 127 My VIN: 1107

Difference - 10 Difference- 19

You can see that within the first 120-135 cars or so produced the numbers were already askew. Factor in a 3rd set of engine serial #s and it is no wonder running production change details are so hard to nail down...:confused:

Thanks for the info Shawn. I had no idea. I thought I would rely on a mechanical inspection for speedo of 140 and nostrils are easy to see and check out for ac but the comment that 57 as a superior vehicle really has me thinking. I have a Mark II that I love and cleary it is time for me to do more research about this. Gary

do u have your eng #'s....we should try and add them to the data sheet

Where are they located and will do once I know how to do it? Gary

That's a good idea. The engine number is stamped into the block next to the distributor. While I have my distributor out I think I'll scrape off the paint to reveal my engine number. I think mine is 4 digits, which means it's a replacement. I understand that that's not uncommon. Continental offered engine swaps instead of rebuilding in the field for failed warranty units.

I read elsewhere that the internal cost of a Mark II engine was $800.00.:eek:

Ok will look next weel and let you know. Gary

My understanding is that ONLY MKII 368 engines have the 4 digit ser.#, the # got stamped on after they were run up and tested to meet "spec". So if u come across a 368 with a ser# is was for a MKII.
