Depends on the car's future use. Just zipping/cruising around town
and occasional drag strip action on Friday night? Nope, 3.50s are a
good choice. If you're planning on some longer highway road trips and
will cruise around in a relaxed/laid back manner 3.50s may be a bit
much. Know that 3.50 gears are considered an "aggressive" street
gear. 3.20s/3.30's are a better "all-around" gear. And 3.70s-3.90s
are the "street racers" gear. Your 2.79s are "highway gears".
So ask yourself... what will you be doing with your car in the future?
Hope this helps.

My A Code 289C4 is running 3.80. I can chirp the tired at a stop
light. What is better for me is longer trips (ie Interstate 5). Takes
me longer to get up to speed (though you'd hardly notice) but, once
there, I can cruise very economically. My last trip I made between 23
and 26mpg and was able to trake it up to about 110 with breathing room
left. Around town, if I keep my foot out of it, I can get around
14-16mpg. If I had my preference, I'd drop it down to between 3.25 and
3.50, which is what is recommend for the normal/regular high side of a
289. Another bad point about the 3.80 is that I have a mild
improvement CAM setup (one stage above stock, and matched to my
Edelbrock Perfomer 4bbl)m and at highway speeds it is LOUD... say
what?... I SAID IT'S LOUD... say what crowd? :0) Around town it's not
bad though. I am glad it's a posi.
