Are 3.55 gears a good choice?

I have 3:55 in 8 3/4 i am running in my rod with 400 poncho motor. The MT tires are about 26.5 " tall and it is a very happy medium compared with 3:73 I took out.
It turns about 2400rpm on highway at 55mph but stiil has great get up and go.If I was rattin light to light I would go with 3:91 or so but all around driveability is great with this combo.

Cheers and gears
Martin
