Are 3.55 gears a good choice?

I have a 72 Demon that was originally a 318 3 speed, the rearend is 8 3/4 with 3.23 gears in it, I am putting a mildly built 340 in it with a 4 gear based on expiences out there how does everyone feel about putting 3.55 gears in it?

depends what you want from the car.

i have a 28" tire on my car.


i had 3:91 gear in my car for a long time. great around town but sucked on long road trips.


put a friends 3:55 in the car and it was quite a bit better but still sucked on long trips and the way i like to drive.

finally put a 2.94 in the car and i love them.. can cruise any where now. i still want a OD though. then i'll have the best of both worlds.. :)
