----If we go with the M40 trans theory (it seems correct) then the other ZL1 would have to be Monaco Orange as it is an automatic and the white ZL1 is an M22 car! Casts some doubt on that Corvette for sure!....Bill S

Any car built before December 9th, 1968 could not be an "RPO ZL1" per GM records (additionally, there are similar records on cutoffs for order placements before certain dates not able to select RPO ZL1 as an option). Now, could a Corvette fitted with a ZL1 engine somehow escape the factory before then? That is certainly possible, but it would not have been ordered or built as an RPO ZL1. Any early RPO ZL1 would also need to have to be built with the correct heads based on the NPC production change specifications effective the date it was built.

----Thanks! I've seen the dates for the Monaco Orange car, but don't have them in front of me, but I am interested in the dates for it as far as the production window is concerned!.....Bill S

I talked to the owner of the Monaco Orange M-40 car at MCACN back in 2018? when he showed it and had paperwork to prove it was an original produced ZL-1 making it (3) total. The Yellow 4 speed Coupe, the White 4 speed Coupe, and now this Orange Automatic Roadster. Is it everyone's belief the Orange Cars paperwork is not genuine? This debate seems to have been going on a LONG time with no concrete answer. I would like to know what everyone on the Yenko.net site thinks. Sure would be cool if it was REAL.

Did he explain why there are two sets of nearly identical documents , one with a font that would not be printable on any printer or typewriter available in 1969? Perhaps it was done for display purposes only while the original was securely home in a safe? That is certainly plausible.

Also why does his tank sticker say RPO ZL1 when the yellow Judski car says RPO L88 then farther down ZL1 ALUMINUM CYLINDER BLOCK? These are the questions that I have around the docs for the orange car that I don't have answers for.

When I see this topic come up I always think of this old post from way back when where Larry (Pantera) commented about seeing a blue ZL1 back then.

If I understand all this and can do the math, we have two stick cars ... one yellow one white, an orange auto and an undetermined trans blue car. All legit ZL1 Vettes.
