Is a 413 Dodge engine out of a 73 motorhome worth putting into a car for peformance?

Not really,,,the engine is not designed to be upgraded for performance and it will be sometimes difficult to get even stock parts for repairs.

The low performance 360 was not designed to be upgraded for performance either, but hot rodders still do it.

The 413 shares the family heritage with the 44o. If the 413 cylinder heads are the normal

automotive head and not the exclusive Motor Home head, the engine can be use for

a performance upgrade from a 318 small block mopar in its stock state. These motors have tremendous low end power but limited high end. They were made to move 12,000 lbs of weight down the street. Any aftermarket parts for the 440 will fit the 413 including the cam, performance heads, intake manifold, headers, carb, etc.
