Best year of mopar trucks?

My wife's 1946 Dodge pickup - before shot - hopefully will have after shots pretty soon.
It was all original, sitting in Washington unregistered since 1973.

It's getting a new frame, mustang II front suspension, ford 9" on a triangulated 4 bar/coilovers, 402 stroker (318 block), tremec 6 spd, got the wheels widened (moved the centers to new hoops) because she likes steelies and hubcaps.
