I have 8 of these in my possesion. All are from turbo Regals. Some hotair and some intercooled. All are this exact tag and codes. I have personally only seen one with the CA8F code and I think it was a fluke and none with the CBCF. The "C" as the clutch would make it stronger with the "330 ft/lb 28 degree travel" compared to the "8" having "300 ft/lb 44 degree travel". I am just presenting what I have in storage and what I have seen and my GM literature. I am more inclined to believe you and Dusty since you guys deal with these more on a daily basis than I have. Not may TRs around this area, especially that are stock.
GM has been known to missprint.
