I am sure this has been batted around before but automatic transmissions are something I have always avoided.
Now I have a 1989 fox body with 5.0 and AOD trans. I am looking at doing some work on the car this winter and will be replacing the stock heads with the better flowing GT40P heads from a Ford Explorer as well as the better flowing intake manifold. Next a slightly larger throttle body, a better flowing fuel pump and regulator, larger injectors, and cold air. And shorty headers with new exhaust. And a new cam. And that is everything (ha!).
I will be rebuilding the AOD so while I am at it I am wondering, what stall speed should I anticipate needing for the torque converter? The cam will likely be an E303 or similar. I am hoping that some of you folks have gone down this road before and will offer advice based on my intended mods. Thanks for the help.

Usually the cam manufacturer will suggest a converter stall speed Trick Flow recommended a 2500-3000 rpm stall speed for my TFS Track Heat Stage 2 Roller Cam. I actually went with a Monster 2800-3200 rpm stall.
