One of the problems with operating just about any PREwar car at high speeds of say 55 mph and faster is that curves in the road such as intercchaange ramps on the Interstate hiways may very well cause a terrific amount of body roll.
To sustain higher speeds (other than in a straight line) will probaby also require getting the suspension tied down. Perhaps just somespring loaded heavy duty shocks front and rear will help.

I don't know. But whe nfirst operating the car with higher interstatee or open hiway speeds just be careful on curves and turns until the car proves itself.

Probably need to set negative caster to the front suspension instead of the oem spec possitive caster.

Check to see what the lowest ratio axle that is availaable.
The car should have more than enuf low end power to never notice the difference. I'm running a 48 motorcycle with 4-1/2 stroke (1200cc) a 3 speed trans and i'm running 3 teeth over stock on the trans sprocket so i can keep up with my friends riding new Harleys. I barely notice the difference at low speeds at all nor even on steep hills that are graveel.

If i could get a 28 tooth in under the chain gaurd i would do it in a heart beat.

Or go with the overdrive.

There is nothing worse than to become a moving obstacle out on the hiway.
