400ci engine in truck vs 400ci in RV?

What are the differences typicall in a 400ci engine in say a old ford pickup vs a 400ci in a RV tuning wise?

Actually The biggest difference you'll see in the RV is 1 oil cooler, trans cooler, power steering fluid cooler, increased radiator capacity. A heavy duty fan clutch and MAYBE and this is a big IF a differently ground cam But again thats a maybe Most RV manufactures used Regular off the shelf factory engines along with the chassis of that same make as the engine unless its a custom motor home Some RV makers made or drastically altered the chassis But the engines or full chassis partial vehicle are sold Whether its ford chevy or mopar were no different internally than the engines used in there own vehicles What was different is whether it was bought as a rolling chassis or cab chassis or just the engines The package was only referred to as heavy duty thats it the biggest difference would be the manufacturer of the engines
