But Steve he asked what was the RPO for the motor option,is why I said ZL-1.
Like when a customer placed an order for a 1970 Chevelle Z-25 SS 396,he received the L-34 engine,(not the L-78 upgrade),which was automatically included with the std. Z-25 1970 SS package,and was not shown at all on the Window sticker either.
Just like if a customer placed an order for the 1969 COPO Camaro package 9560,they automatically received the motor option ZL-1 right at the factory,and not the L-78.(although the car received the L-78 ornamental treatment for obvious reasons)

Here is the description for RPO Code ZL1:

The ZL1 Camaros used a COPO number . . . NOT an RPO code. You can easily see this on the paperwork provided.

So tell me . . . what does RPO stand for? Does it stand for Regular Production Order?

It's the same thing with the 427 Camaros and Chevelles. Nowhere does L72 appear on the paperwork. Only a COPO number.
