I wouldn't be so sure Loco - up here if you put a newer engine in any vehicle it has to meet current emissions standards, regardless of the year of the vehicle - the '46 trucks didn't come w/ a modern V8, so it's pretty obviously no longer a "46" truck - down there I'd think it might vary by location
the question tho is really can you buy a crate motor today that doesn't hafta have all the emission controls to run properly, and will it work well w/ duals - the answer to that is yes
