I got excited when they said
"The orginal straight 6 and original tranny was still powering the 15000 lb. bus and they drove it with this powertrain for several years until a 304 ci international engine and international transmission were installed. This propelled the bus to an unheard of 80 mph for a '46 bus. Soon after the original rear axle burned up so a '46 logging truck rear axle was installed featuring split gears (high and low). A new interior was installed and a fresh 2 tone paint job made the old bus look incredible. Also installed was a roof mount air conditioning unit."
Then was disappointed when they said the engine was taken out
