Ridder higher stall than cruise rpm does "heat up" a non lock up converter such as in a 3 speed transmission because its always slipping which does lead to burnt or premature wear of your trans fluid which if left unchanged will lead to the premature death of your tranmission /converter. This is one benefit of an overdrive transmission such as the 200-4R or 700-R4 in that they come with lock up converters. Another thing that makes them ideal for a hot street street strip kind of car. Also the lock up usually saves about 200 to 300 rpm and is often worth about 1 mpg on the highway.
JBreu I hear you on the low first gear of the 700-R4 and the 4.10s but that is mostly a traction issue ie if you are hitting too hard for your tires. You say max torque at 4000 rpms. I would try a 3,000 stall lock up from any of PTC Coan Red Neck converters or generally any converter builder recommended by your transmission builder. FWIW I am not a fan of TCI especially for converters. You could benefit a little in the quarter from an even higher stall but then lock up usually either goes out the window or becomes cost prohibative.
