The engine should be green, IIRC. The Power Pak was a Passneger option, not offered on trucks. However, the Taskmaster 283 did use the same 4bbl Rochester 4G carb as the Power Pak cars did, only with a manual choke. But that's about as close as it gets, cams and heads are different.
The only Power Pack reference (note the different spelling) I've ver seen inreference to trucks is the Napco conversion, which was also referred to as the Mountain Goat in the AD trucks.
