MSD Distributor timing curve setup

[7Dcuda]

Im about to install a full MSD ignition setup with the Pro Billet Distributor in my 70 Cuda with a street build 440.  With the timing curve springs that are included with the distributor and going by the timing curve charts, for my application, I can curve it to be "all in" at 2,500 RPM, 3,000 RPM and 3,500 RPM.

Which "all in" RPM range have you guys found to work best with street build 440's?

Depends on what you are doing with the car, is it a street car, race car or?? what trans? what gears? etc. If it an AT, what is the stall on the converter? All this said, on my 70 Challenger I think I am at total advance at around 2200-2500 (AT car, stock converter, 3.23 SG).
