The 12V-92 was not offered in the General or Bison. Fuel economy, or lack thereof, would certainly have been a factor. But, I think the main reason was no regular highway transmissions at the time would have stood up to a 12V-92. Size and weight were probably a factor as well. Unlike a 12V-71, a 12V-92 has 4 cylinder heads and a longer heavier block. It just wasn't a highway engine.
