Cant say for sure, but my guess would be cams and compression if anything... maybe just valve timing.

The "heavy duty" engines in the f600 and higher trucks have a larger exhaust manifold and possibly lower compression pistons than the passenger car 300, but everything else is the same. The f-series pickups all use the smaller exhaust.

Yes. It is a good upgrade from the passenger log manifold.

The 300 was never available in a "passenger car". In vans, yes, trucks, yes, passenger car, no.

The 240 was available in Fullsize Ford cars 65-74 but not the 300.

Sure. We're getting into legal vs descriptive language. Parts catalogs call it a passenger car motor, and most pickups/vans are registered as passenger cars, vs the official truck designation on a ten-ton box truck.

The "ten ton box truck" 300 got the big manifold. The "your grandma would drive it" got the small manifold.

It's simple the 300 never came in a car. Even if it should have!
