Matt, that's a nice looking wrecker. Should be an interesting build when you get to it.
As for the General in Coke livery, I'm not sure if Coca-Cola would have sprung for the 116" BBC hood with the 8V92N & a sleeper. My personal opinion is that they probably would have gone "fleet cheap" and gone with the standard 108" BBC hood (available from Gary Wallace) and the standard 6V92T engine; but that's just my opinion and you know what they say about opinions.
