4,889 L78.....does not include another 311 with L89


per Chevrolet SS Muscle Car Red Book

Besides including the 311 L89 cars I believe the 4889 # also includes both 9560 and 9561 Copo Camaro production too!.

Like L89's, Copo Camaros were RPO L78 cars first before 9560 & 9561 was added to the order thus why the RPO L78 by vehicle # of 4889 is higher than the grand total of Tonawanda engine production totals by Suffix for L78 and L89 added together even w/ their totals including service engines too!.

L89 was not an optional engine; it was an aluminum cylinder head option requiring the L78 engine. Both L78 and L89 options appear on factory documents for these cars. It is my opinion the L78 total includes those built with L89.

Conversely L78 does not appear on factory documents for COPO cars; it was not required to order one. I have no idea why they would be included in the L78 total.

What is the prevailing thought on the 311 L89 number as in relation to 311 Camaros, or a combined 311 Camaros, Chevelles,and Novas? Don't start on the Novas. Just asking on individual models, or all inclusive.

If I'm wrong I'm fine w/ it but here's how I'm seeing it..

If the 4889 # represents '69 model year F-Bodies shipped w/ RPO L78, I'm in total agreement it includes those built with L89!.

As for the the 9560/9561 part, GM Canada Vintage services paperwork prepared from microfilm for '69 Copo cars by Vin also indicates L78 like the L89 equipped cars do!.
I have a copy of one of the Canadian Vintage services sheet for a Copo car that clearly shows RPO L78 also 9561 as shipped w/ the car..

Fran P and I discussed this 15/20 years ago and expected this may be why Tonawanda engine production by Suffix totals for 1969 L78 and L89's weren't enough to supply the total of 1969 F/X cars ordered w/ RPO L78/L89 but never did get the #'s all together and do the math like we'd hoped to..

As far as the L89 # 311 goes, does this represent F-Bodies shipped w/ RPO L89 or a Tonawanda engine production by Suffix quantity?.
If it's a Vehicle RPO # and the 4889 is too, the 311 can be subtracted from the 4889..
But if the 311 is a Tonawanda engine production Suffix # it would include service engines built also could include X-cars if there were any?.

Anyone here have the '69 Tonawanda engine production by Suffix totals for L78 and L89 F/X cars?.
If L78/L89 F/X engine production wasn't enough to supply the RPO's ordered, if we can get all the #'s together lets do the math and see if the 9560/9561 thing is actually possible or not?.

It has been talked about B4. It always puzzeled me that both Camaro and Chevelle use that 311 #. My guess is the 311 came from Tanwanda records, and maybe it was 311 total engines shipped. Think about it, how many real L89 Chevelles have you ever seen ?
