The attached broadcast sheet in the following link:http://www.camaros.org/forum/index.php?topic=3932.0
was recently found on a 1969 RS Van Nuys built car on the gas tank. The engine code is HD (block #172 on the broadcast sheet) and if I'm reading the carb application code correctly it is DD (block 176 on the broadcast sheet). In 1969 HD is the engine code for the L65 with TH350 tranny.
The owner of this car and I have exchanged e-mails and I believe that he will be posting some detailed pics of the carb. From pics that I have already seen, the carb currently on the car is indeed the Rochester 2Bbl, SAE 1-1/2" variant.
This has been previously discussed at: http://www.camaros.org/forum/index.php?topic=3006.msg22733#msg22733
. This car provides additional documentation as to L65 carb. application.
This car also has RPO C60; air conditioning. According to info. currently in the CRG Report, 350/250 engine with auto tranny and air conditioning used carb application code DF where this broadcast sheet indicates DD (if I'm reading it correctly). In the report, DD is shown as correct for 350/250 with auto; without air.
