I just picked up my car. I guess I'm in the club! Love it! About 60 mph@3,000 ! I guess I've got 4.10's or so. Is a 3.55 too high?

3:88 seems to be the right ratio but depends on the tire size, torque and HP of the motor. I just sold a speedster with a 2180 motor and a 3:40 trans, that thing hauled ass.
3,000rpm at 60 mph is about perfect.
Remember, this is an AIR COOLED engine - the faster the engine turns, the more air flowing over it from the fan to cool it off. 3,000 rpm is a nice engine speed to start at. Use your gears to keep it there or higher. 2,500 is sort-of OK without a lot of load (just coasting along) but try not to drive around below 2,500 rpm. That's why you've got a gearshift.
Keep those revs up - Keep it cool.

Yeah, I also don't want to pop this thing either! Its a good around town gear, but to keep from getting run over on the breif highway miles, it was 4,000 at 72 or so. Yikes!
Speedster owners gotta change their mindset when they fire up the air cooled ride. I've got a 3/4 ton truck that hauls 80 MPH at 2200 RPM. DON'T EXPECT SPEEDY TO DO THAT!
Carbs, air cooling, oil cooling, sometimes 60 year old technology requires 60 year old solutions. Just pretend you've been transported back to 1957. Take a backroad and enjoy the ride.

No not at all... When I climb in our 70 Cuda , I drive in 1970!! Hell, I almost put an ascot on and turned up my collar last night when the wife and I went out , as it was a bit balmy... However.... I refrained from any such nonsense! Hahah
My car was pulling 3,800rpm at 66 mph (our speed limit in Western Australia) and on long runs combined with a Monza exhaust, it was too tiring.
Soooo I have ordered a rebuilt and strengthened transmission from Rancho with a 3.44 diff and am now on the hunt for a 2.1 type 1 to replace my mildly modded 1700cc type 1.Hopefully, this will have enough torque to cope with the odd small hill we have around here.
From all my reading on this site, this would seem to be a good combo for someone who prioritises cruising ability.

I think that 3.88 sounds like a good compromise to me... my 1776 doesnt feel like it would like a 3.42ish gear.
4,000 RPM=72 MPH---you should be getting great cooling with that engine speed.
For 72 MPH I'm seeing just 3,300 RPMs ---oil temp max is 185 with 90 degrees OAT with CHT of 400 so I'm still getting good cooling.
4,000 RPMs gives me 88 MPH.
I do like this combo, especially for highway speeds.
