Default 3.27 ratio in slow traffic

I have a lighter weight body style with a fresh build B engine. I have no doubt that a 3.27 gear would work well on the open road for me, but question its practicality on tour with "regular" cars. 80% of my driving is in groups that travel 40 m.p.h. I see this scenario causing a lot of lugging of the engine, especially on grades. Is the jump from the 3.78 that drastic, or am I making something out of nothing? Thanks fellers.

My opinion is you will be unhappy with it in that scenario. I use the term "unequally yoked" in that with 5 Model-A's in the group that all are shifting and accelerating at the same basic pace, you are at "odds" with them.

Unfortunately I have this same situation with my 18 y.o. son's Model-T truck. When he is by himself (--or traveling in a group with his sister, and with Pennie & I) the truck runs out really nice but when he gets in a tour environment where there are cars around him without the same power nor gearing, he is constantly running up on them and tailgating.

I agree with Brent. Back in the 70's (before kids) we went on numerous long trips with the club. We typically traveled with a speed goal of 47 mph. Whenever we going through the mountains many of the folks would tend to fall back to the point of lugging in 3rd gear. I had 3.54 gears and would often be forced down to around 30 mph on hills which left me 'between gears', too slow to climb in 3rd and uncomfortable running steadily in 2nd. That left me with two choices. I often chose to pull out of line and run up ahead then wait which didn't please some folks but it was either that or fall back.

Even with stock gearing I wouldn't have been happy but the problem would have been slightly less frequent.

These answers make me feel better. I have 3.54's in my Tudor and like them on tour. Not so tall as to make trouble, but there for 55 if I wish.
3.27's would probably be overkill in my situation.
Happy motoring.
