Ex trucker with caterpillar engines and long term Duramax original owner LBZ dude I have stumbled upon a 1990 7.3 which I believe will fall into the IDI category. I know not much about them and am curious about the obvious things like durability, fuel mileage and parts costs. HP and torque specs. I believe it's a stock engine and it's in a motorhome. Good choice? I found and I am currently reviewing the Newby to IDI thread. Look forward to getting to know a few people here.
