Word of caution, many forum members have given up on Clifford lately. since the original owner died, things have not gone well.
Since you're in cold country, you should start with an electronic ignition upgrade, to help start on those cold mornings.
The two most popular are the later model Ford distributor complete with box, etc (Duraspark), or the Pertronix Ignitor.
The pertronix kit is easily installed in place of the points, and works quite well. I liked the idea that, if it ever fails, I can just pop the points back in.
Get the Flamethrower Coil too. New platinum plugs and wires are also a good idea.
If you're not ready to replace the carb, do a rebuild. It's not that hard to do, if you can read an in struction sheet. Make sure you replace the plastic float with a brass float, as the plastic becomes porous over time. A K&N air filter won't hurt.
Before other chassis upgrades, get the front end stabilized by adding an export brace. This will keep you from chewing up front tires from shock tower flex. Next comes a 1" sway bar to keep you level.
Next, locate a donor car, such as a later model Torino or Granada, so you can swap in the 5 lug disc brakes and rear axle.
Once you can stop and handle, go get that OZ head, headers and a hot cam.
