Suggestions on performance upgrades for 225

Hey fellow FABO!
I have a 1965 A100 w/a stock 225, 3spd on the column, Sportsman Camper. It is a solid van with a great running, shifting, motor. But, I want to up the torque and hp a little...nothing serious since it's mostly a "around town" driver, but I would like to get her on the highway but not with it's current configuration.

I've recently found Clifford Performance and their combo-package (intake/exhaust/2bbl carb set-up) and thought that is wasn't far from my budget and everything is pretty much "bolt on". THEN - I found FABO and everything I've been reading is fairly negative about Clifford's intake and exhaust manifolds.

So now I'm back to square-one and hoping for some sound advice and suggestions for easily obtained performance parts that come recommended from the community. *I'm open to additional performance suggestions like gearing, cam's, 4bbl over 2bbl, etc.

Thank you in advance for all your help.....I'm super stoked to be a part of this community!
