That they did, the 7.3L with 4 bolt and cross bolted main bearings, forged steel crankshaft, aluminum heads and a bore/stroke ratio that produces high horsepower and strong mid range torque that is far more fuel efficient then the GM 8.1L offering. You'll notice the 8.1L hasn't been offered in 3/4 or 1 ton trucks since 2006 and therefore GM doesn't really have a gas powered TV to sell other then the 6.2L V8 which is not that strong towing over 10k trailers while Ford is still offering the V10 in the F550 and F650 trucks.
