1970 Chevelle LS6 Convertible

[bergy]

4th week of February car and a 3rd week of march dated trans case

[Ls6 Ragtop]

What I believe Bergy is referring to on the trans case is the casting date that's represented by the dotes in the 12 squares on the side of the case which if I counted correctly are eleven which translates in March of 70 which would make the assembly date of Feb. 9th impossible and not surprising given the horrible restamp of the shown vin #. I have a real M22 case with the same casting date and an assembly date of P0D15C for reference. Distributor shown is a bad restamp as well. Block stamp is interesting, terrible condition but interesting.

Looks like Bergy beat me to the answer................

This car could be one of the cases that I've seen too many times in the past few years. Someone will take a car that is real and quite special and embellish with fake paperwork or restamped parts added that bring on undue speculation. I must agree with Chris on this one, if that block was restamped it was certainly not by the same "craftsman" as the transmission. That Kc vin stamp appears to be accurate compared to others from the plant at that time. Are there any known real LS-6 convertibles built in KC? Any that I've seen were Baltimore built cars.

Exactly. Unfortunately too, the pad is in such bad and pitted shape

I owned a triple black one years back sold out of Van Chevrolet, so there was at least one. It was an M-22, matching number &quot;12C&quot; car, so one of the very first built.

Ls9 Ragtop is, of course, correct. The casting date grid is divided into 12 &quot;boxes&quot; which are created by 5 vertical lines and one horizontal line. The top 6 boxes represent January through June and the bottom 6 are July through December. At the beginning of each week during the production year, a pattern maker would strike the die (these are permanent mold castings) with an additional punch mark in the appropriate month's box. So, 3 punch marks in the March box = 3rd week of March. It's important to remember that casting inventory wasn't controlled on a &quot;first in - first out&quot; basis, so a delay of up to 6 months from casting date to assembly date is permissible. Different permanent mold facilities used different style grids, but usually the same &quot;punch&quot; method was used to designate succeeding months.

IMO - The engine stamp appears acid aged - the depth of pitting is severe and pretty selective.

My guess would be that the rest of the car probably looked about as bad as the block before receiving some new sheet metal.

I noticed the buyer of the Fathom Blue LS6 Vert at Mecum this weekend even had the build sheet undergo a forensic analysis by a document specialist.......smart buyer. That car by the way was a Van Nuys car so certainly Baltimore wasn't the only production site for these. As a matter of fact, I still recall the earliest LS6 Vert that has been documented and talked about on various boards was a Van Nuys car. I remember this because it was mfg. one day earlier than the LS5 Vert I used to own which was also produced in Van Nuys.

Dick,

Curious of the build date of the early VN LS-6 vert you mentioned. Mine was a 12C car, so certainly was a very early one as well.

There was quite a bit of research that went into the Blue LS6 Convertible at Mecum.

I believe that Buddy had two similar looking chevelles.

I'll start a new thread on the real one.

This is also an Los Angeles built car. I don't recall anyone questioning that the LS6s were built at more than one plant.

I was the owner of COPOs former LS6 and it was documented all the way back to the original owner who was in jail at the time.
