6T3 Nova,
A 250 would be a good start.
It will bolt right in & make much more power than the 194,& still get decent gas milage.
A 292 requires a bit more custom work to drop in.
Mainly just your pass. side engine mount.
It is pretty hard to get good gas milage w/a292.
But w/a 292 there is more potential,bigger cubes,4.120 stroke.
It just depends on what you are looking for??
