Those are BIG truck engines and will not fit in much else. The 360 is the only one that would even qualify for the vintage class at Bonneville since there is a 375" limit. Years ago I got a 413ci Dodge flathead six with the Idea of playing with it in a vintage class at Bonneville. There is a 375" version of it, just a crank change.
Otherwise it would be in BG lakester and tires aline would be over 3Gs. I even had an Honest John missile nose cone for it.
I doubt that performance wise the extra size and weight would be helped by the extra inches. Maybe I'm wrong.
