I have 4.10 gears with a turbo 350 transmission and 28"
tall tires. I run about 3,500 at 65MPH with a small block. I don't
like it but chose this gear ratio knowing I was going to swap in a 4L60E trans
giving me a cruise rpm of about 2,600 at 65MPH. A taller tire will
only help. 3.73 is still a fairly steep gear and I agree with John would
be considered marginal with a 1:1 final drive ration trans such as the
TH350/400. If you ever plan on swapping in an overdrive trans it would be
worth the short term discomfort of high rpm cruising. It's more difficult
to change gear ratio than trans in my opinion. I set up my own diff and
it's a job by yourself in your garage on your back. Hope this helps.
I would stick with 2,500 rpm as a target cruise rpm.

overdrive trans doesn't mean you won't,Ryan. It's only money.
