Good morning TM. First off, great find on the ‘46. That has been one of my all time favorite trucks since about’74 when a classmate had one with a little Z28 302 in it. He could lift the front wheels on launch, which to my 17 year old self was about the coolest thing I had seen.
I have a ‘50 1/2 ton I have peeled down to the frame. I’m going much the same route as you seem to be, but sticking with an inline 6. I bought a Clifford Performance package for a 292. I want enough HP to move my truck down the road but didn’t want to go the old “everybody has one, so I will too” route of a sbc under the hood. I want to pull into the parking lot and have people wonder what the heck I have under the hood, and then shock them out of their shoes when they see the inline 6.
Do you have your truck home in VT yet?
