These are variables in all cars,so they will affect "How Fast" you drive. I've heard to keep the motor between 1800-2500 RPM's. With my roadster, 3.78 rear 7.00-16 tires, 47-53 MPH is 1800-2500 RPM's .Can I safely "push" it Harder?
Mine will cruise nicely at 65 all day long. But it has a 3:54 rear in it and 7:50-16's on the rear. I also have juice brakes 6:5 head, magneto, and a '39 box. Before I changed the car to this configuration 50 was as fast as I wanted to take it. Stockers like 45-50. If you want to drive it faster you need to change a few things, but they take right to the mods and if you like to drive on the freeway or long distances you'll be alot happier.
