Around town, sure, but it'll be a damnuisance on the highwaythe engine will be screaming (and guzzling fuel).

I ran 3:91's with a 26" tall tire for a long time with my 340. Now with 28's my big block is pretty happy.

3.55's and a 26" tire is about 2900 RPM at 62 MPH. What's the big deal with that?
