Advice on potential gear swap
i think the best compromise gear is always 3.23, but i can certainly see the appeal of a 2.94 and i don't think i would personally go to a 2.76 unless i was specifically building a car for long haul road tripping.
given your cam specs, with those long legs it'll change the overall behavior of the ride for sure. while you won't have to mess with anything else (shifter, converter, ect) you'll likely need to adjust your tune to accommodate.
