My truck ('66 Chevy C-10) is finally nearing completion. It's should be at least 100 hp stronger than original 165 hp, and maybe 120+ more.

The 3-speed column shift transmission is retained. There is no overdrive gear.

I'm not sure what the final drive ratio is, but I'm considering changing gears for a TALLER ratio. I don't think I've ever heard of anyone swapping stock for taller gears, but I'm thinking that with so much more power under the hood, I'd be much happier at highway speed and not really pay any penalty in acceleration and driveability, especially since the 3-on-the-tree doesn't make for quick shifting.

I do plan to tow some with it. Say, 3000 lbs of boat.

What do you guys think?

first thing to do is find out what rear end ratio you have now and what the 3rd gear ratio is on that transmission (1:1?)

but i have heard of plenty of guys doing this to reduce RPMs at highway speeds on older trucks. like you said, yeah, you'll give up some acceleration, but the increased HP should more than make up for it.

go for it

might be way more complicated, but what about a push button OD from something from the 80s?

Seems like keeping the column shift is a priority. Ditch the column shift and you have tons of options better than that^

can also make rear end ratio seem taller with larger circumference tires in rear...
