’86 factory “high-stall”?

Its out of a 86 360/727 pickup and I think its stock. It has a little round sticker on it about 1" and says "HIGH STALL" with a sharpie line between them (over and under) What is the stall rating so I can match it to a cam? Doing an Edelbrock Pro-Flow injection 402 and itll see the track maybe once just to get some "closure" ;-) Cam to follow but maybe a Crane 284H12 I have.

3000 lb A 3.91 rear auto.
