I will pull the engine at some point, and will continue to document it as I pull it apart. Although it's unlikely the engine would have been pulled and painted without being rebuilt, especially with the car's low mileage, anything is possible and until I inspect the rear face of the block I won't come to any conclusions. I have only had it apart as far as the timing chain. The timing chain was original GM and the cam is original GM 067, and it's likely that even a re-ring would have replaced these items.

The bottom of the intake runners had remnants of turquoise blue non metallic paint visible on the runners.
