1952 truck tranny

[Patriot1]

Guys, I'm new here and could use a little help. I just picked up a '52 Chevy truck with a stock 235 and a 4 speed. I'm told the tranny actually came out of a bus and it's geared so low I can start off in 3rd gear. At about 45 mph it's screaming like my ex-wife with the fuse on her tampon lit The trucks going to be a daily driver so I need to be able to get up to highway speeds comfortably. Any suggestions as to what 4 speed tranny I can drop in there to match up to the stock 235? Any suggestions would be greatly appreciated. Thx.
