New guy questions.
I have a '41 Special Deluxe and plan a 292/T5.
It has to have a period look with modern concessions for safety/reliability.(i.e. multi carbs on modern 6, HEI, disk on IFS. etc)
I want to make it a road car, and MPG is important.

1) should I be considering a 250 or 292? (the bible says 292)

2) T5 or possibly a 3sp/OD column shift. (no slushboxes)

anything else?
