General Discussion / Z/28 engine pad stamp codes..
« on: September 11, 2020, 12:35:52 PM »
Was reading some stuff on a Facebook discussion regarding 1968 (all 3 years of 1st gen actually) Z2/8 engine code stamps, and someone came up with MI after all of the regular MO, MP, and DZ, codes were mentioned.
Apparently they claim the Estes' Z convertible has an MI code assigned to the 302 block and they claim that proves it is a valid code for Z2/8 engines thusly.
Firstly - does this 'one vehicle' in fact have an MI code stamping and does it have a regular 678 engine block casting number??
Secondly - we all know this is a valid, yet oddball vehicle. Should it in any way be considered a 'production vehicle' or one that should hold any significance as a valid type or model for the 1968 production year?
and..
Thirdly - some have commented that this particular car is or should be considered a COPO car since it has this MI code and in fact are saying that MI is a code designated for a COPO vehicle by GM?
I would love to hear any thoughts regarding this particular car - and it's unique code or designation if in fact MI is truly the stamp on the engine block.
I personally consider this car can't or shouldn't be considered a COPO because it wasn't ordered through the dealer or COPO system - instead it was probably concocted as a on-off or test vehicle status considering it was the only example made, and that it probably like many was probably slated and destined to be crushed at some point like many other 'test vehicles' GM made for evaluation and then finally destroyed after a point, never truly considered to be a long term car for public sale..
All comments and/or details shared are greatly appreciated!
