As to the latter, the bluebook says $120,000 to $160,000 per side, and that's a lot, but I've heard horror stories — some apocryphal — suggesting that once the engine is opened, it is not uncommon to hear that the price has escalated. This information comes to you, they say, once your engine is in pieces on the shop floor. I find this overhaul prospect both financially frightening and, in another sense, slightly ironic. It's frightening because these are uncertain times for all of us and we're talking a lot of money here. My retirement account is a shadow of its former self. It's ironic because, of all the maintenance issues, repairs and glitches that we've had in 10 years of Cheyenne ownership, the engines are about the only bits that haven't required unscheduled interventions.
