Hi,
I just finished a Chrysler 75 1929 withg red-head. We have done this year a LeMans Classic with this car.
The engine work great and has a lot of power but the car is slow. It drives about 90KMH by 3800RPM.
My car has an oryginal gearbox and diff ratio.
Do you have any information what diff ratio has a car oryginally when driving Le Mans in 1929 ?
