stall converter lockup - Third Generation F-Body Message Boards

I'm going from the stock 305 with TPI to a carbed 355 setup. My transmission is a built 700r4. I recently purchased a 3200-3600 vigilante lockup stall converter.

My question is with a stock setup, when does the converter actually lockup? Does it lockup under WOT and when cruising? Also, since I have swapped to carb and am lacking a computer, am I going to have to manually toggle the lockup action of the converter?

Thanks.

The stock setup locks up the converter in 3rd or 4th under cruise conditions. It unlocks when the brakes are applied, it downshifts, or you accelerate. B&M, Painless, and TCI all make kits that control the lockup in 4th gear automatically with no computer required.
