1968 COPO nova

[copo-2]

Thank you for all the details. So, were all internal engine pieces such as camshaft, pistons, compression, etc left as delivered from the factory?[/quote] Knuckledragger

Unless specified differently, it would be my belief the 396 version that authorized Chevrolet dealers sold, were modified mostly by visible aftermarket parts, except for the carb & distributor? However, when we think about the fuscia race car, for example, that would fall into the catagory of what the customer might wish by paying extra, who knows for sure? Things of this nature, without work orders or some other form of documentation, would only be a guess? I'm pretty sure most had a basic tune and options as can be seen on pg 17 that Greg posted in the PHR article of Nov. 1968. This article does mention the 427 powered street/strip version, with optional engine extras available. Again look on pg. 17 at the 427 version test car and note the camshaft specs.
