A C-10 with a 292 would probably have to have been special ordered when new. I don't think it was normally offered in the 1/2 ton trucks. C-30 and up would have been a more likely candidate for 292 power. They are rugged, powerful engines that will give a V8 a run for its money pulling a load, but they love their gasoline!
