Get the 5-speed.
Typically they have a deeper 1st gear than 3- and 4-speed trannies in addition to the overdrive top, so there's a little more "oomph" off the line. And typically the shift action is smoother, as the linkage is all internal (no road crud gets into it to wash out lube, wear bushings, and make stuff rust.
Put a 4-speed shifter **** on it and modify either your existing shift handle or a 60's-era aftermarket 4-speed handle to fit the 5-speed tranny (this might be easier than you think, possibly as simple as drilling the two holes in the shift handle slightly oversize to accommodate the slightly different 5-speed handle bolt spacing. I can get a picture for you if you'd like).
Nobody will ever know unless you tell them or if as passengers they're paying attention when you make a seemingly "impossible" upshift (it's almost worth doing just to watch their reaction
).
You might need to get a 5-speed **** if your state inspection involves an inspector driving the car.

2 ?s
1. How much do you want to spend.
2. Is this a DD car?
The 4 speed is a direct bolt in and will be your cheapest option.
The 5 speed will require a little work and money for everything to make it fit in the car. The 5 spd will do better on gas if it is a DD.
Personally I would rather have a 4 spd. Find a close ratio one and it is a ton of fun to drive.

Check www.davidkeetoploaders.com for rebuilt or new 4-speeds.
Used car part prices are all about what the buyer is willing to pay (if you can find a buyer).
I would be surprised if you'll get more than 1 or 2 Franklins for the 3 sp. Most want to upgrade, like you,,,to 4 or 5 sp.
You may get lucky and find someone who really really needs one, try Ebay.

if you want the 4 speed for its ability to keep those racing revs up a t5 would be even better. along with that 5th gear overdrive you get it has a lower first gear to dig in even more bc it can get away with it due to the 5th gear. the t5 is the way to go. if you are concerned about looks, you can throw a 4 spd **** on it, you can redrill urs or you can buy one that most suppliers will have. the t5 is the way to go

Last I looked, nice rebuilt 4 speed toploaders run around $1800 w/o clutch and pressure plate. A used 3 speed would probably bring $300-400 because it is basically a core. If you can convence someone your used tranny is ready to drop in and use, you may get a little more, but most people are not going to be that trusting.
