What gears for a c-4?

[Rev]

I use a 3.25/1 in my '66 coupe with the C-4. I don't want to spin more than 3000 @70 mph when cruising. I do use a TCI Breakaway convertor that's supposed to stall at 2500. Mine actually stalls at 2800 because I have a little extra torque down low .

For a street car, be conservative on the cam. Build the engine for good low end torque with 5500-6000 peak power.

The thing to remember is you can't have it all. With the C-4 and no over drive, I would stick with 3.25's and try to aim for good low end torque and a mild torque convertor.
