Re: L72/L78/COPO production dates?
Excellent info, thanks!
I'm trying to figure out some date code issues, specifically regarding 4346 Holley carbs. If I understand correctly, the last `69 COPO Camaro was either Oct or Nov. `69 built, right? Were there any other 1969 model year L72 or L78 (or COPO) cars built after late 1969? If so, how far into 1970 did they run? I'm trying to figure out if an 01 0r 02 dated 4346 carb could legitimately be considered a "production" dated carb as opposed to an early service dated unit. Thanks again Eric [img]/ubbthreads/images/graemlins/beers.gif[/img]

Re: L72/L78/COPO production dates?
My 70 L78 Camaro is an 01C car, VIN is 506xxx; CamarosRUs has an L78 01C car, VIN is about a hundred different from mine.
It seems to me that I have heard of several June 1970 built L78 Camaros, but I can't find any notes on them at the moment.. -Sam [img]/ubbthreads/images/graemlins/burnout.gif[/img]

I cut up a 70 camaro #00523 for the back wheel well tubs for my 70 car. The back halve was perfect but was hit hard in the front. [img]/ubbthreads/images/graemlins/eek.gif[/img]

Re: L72/L78/COPO production dates?
Again, thanks for the responses [img]/ubbthreads/images/graemlins/smile.gif[/img] The knowledge available on this site amazes me. [img]/ubbthreads/images/graemlins/worship.gif[/img]
Let me see if I understand this correctly... So there weren't any 1969 model year L72/L78 cars (of any body style) built after Dec. `69 (during the Jan-Feb 1970 carry-over)? Is this correct? (I know the L78 option was available on the `70 model year cars, and the LS6 replaced the L72 option.) Sorry if I confused anyone. Thanks again Eric
