I have run big stalls (3500) on the street with a 310/314 roller and it was a pain in the rear end. Depending on your cam and how hard you want to launch will be more of the end result. Yes, a dyno is the right answer but you can get close. Stalls also have true stall and brake stall. I have a great article I can scan in and email to you if you would like.

I have a truck. I have a decent sized cam (see post - a 292 and it is driving me nuts). I run a 28 inch tall tire, 3:73 gear and a 2500 converter. Enough stall that I can pull against the brake and get some traction since I have no weight in the rear end but low enough that I can still drive freely. It has been on the interstate once (different cam) and she was good to about 60-65 without feeling like I was punishing it. If you want to do much interstate driving look at a 700-R4. Lower 1st and 2nd gears along with a 4th gear overdrive. You can run a smaller gear (3.23 instead of a 3.73) and still get the same launch capability.
