How to determine the needed stall speed?

What do you guys use? All i could find was that you wanted 500-750rpm below the peak torque curve or go by the duration of the cam.

One site claimed that under 220 you don't need more than 2500.

So my cam is spec'd at I224/E23-, so should i be shooting for the 2500-2800 range?

There are a lot of factors that determine stall speed. Yes the cam is one, but you must also consider weight, gear, and what you plan on doing with the car. As an example, I have a relatively small cam in my car (216/224) but my converter is set to stall at 3400, roughly 400 below peak torque.
