It all depends on what you are comfortable doing. You can pull the six for a rebuild or purchase a remanufactured short block and reinstall your cylinder head.
You can also remove the six and install any of the Ford small block (221-260-289-302-351W-351C-400) or FE (332-352-390-406-427-428) V8 engines as well as the 385-series (429-460) with a bit of modification.
Note that the swap from the six to ANY of the V8's is going to mean substantial expense and work in the area of radiator, radiator brackets, engine frame mounts, throttle, clutch and shift linkages, fuel lines, front and rear brakes, springs and shocks, rear axle housing and differential, underhood wiring, starter motor, accessories and brackets (alternator, power steering pump , etc.).
As far as transmissions, you'll need the appropriate manual transmission bellhousing and the '67 3.03" 3-speed will be satisfactory for most any of the V8's, provided the correct size input shaft is used for the engine application.
In short.... unless you have lots of time AND money, stick with the six. If you're looking down the road to doing any further modifications you can look to swap in a later 200 six (aka 3.3 liter) from a late seventies/early eighties Fairmont, Zephyr, Mustang and a few other models.. they have bellhousing pattern compatible with the small block V8's so transmission choices are much greater, including the T-5 without as much "fuss" as behind the small six bell, larger clutches, better starter motor choices, larger diameter intake manifold, etc.

What, me worry?
