Thats like saying that it does not matter if the head boles in the engine are loose because the pistons move a lot of air.
That guy needs to be ran out of business, after he repairs your trans, gets you a new converter and you watch him torque the valve body bolts.

How big is your cooler, and are you running the trans fluid through the radiator tank and then through the cooler?
Back in the 70's I ran a B&M J 5000 stall on the street all of the time and it was sweet.
Talk to Rick at A&A transmission and have him build you a nice 3200 stall convereter.
