I had the same concern with my '57 but a sml block v8 and 3 speed on the column and 3.55 rear end. I was about to install a 3.08 rear end ($1k)simply to reduce rpm when a friend set me up with the old technology manual trans. Borg Warner R-10. It reduces RPM 29%. Basically adding a 4th gear. Has idiosyncrasies,
but worth it. I did not have to alter drive shaft

I DO NOT know if the old R-10 will fit on a 6 cyl without research.
a cheap option is to get tall tires on the rear but your speedometer reading & riding height would be off but you can check mph via GPS.

Some guys on chevy talk reeaallyy helped me get mine going. The were so knowledgeable, I could look up the old posts and you could ask them questions.
