Successful use of aluminum flywheel on the street:
1965 Valiant sedan, 3100 lbs., 340" LA engine, 350 hp?
Chrysler 833 4-speed, 3.09:1 1st gear
Chrysler 8-3/4" axle, 3.91:1 ratio.
Torque multiplication in 1st: 12.1:1
Blip the gas, slide the clutch out, done.
If your 1st gear X axle is less than 10, you want a steel flywheel or different gearing.
The sensitive part of the carburetor is the primaries. If they're small enough the car will have good manners.
2 bbls. only have primaries, and they're larger than the primaries of a 390.
