Factory High Stall Converters

The dealer I worked for took in a nearly new 1978 Cordoba 360 wreck, completely totaled. I bought the transmission because I was aware of the increased stall speed I had to knock the counterweights off from the converter before installing it in a stock 69 Barracuda 340-s which with the 69 oem 727 formerly stalled at 2550 rpm which was enough to smoke F70-14's. With the newer 360 trans it stalled at 2650 rpm. and was noticeably peppier. Two years ago while restoring the CUDA I replaced the stock 340 with a well built 11.3:1 470 3.915" stroke BB with 246*@.050 cam. After building up a BB 727 I used that same 1978 360 converter and now it stalls at 2900 rpm behind the high compression stroker and launches with authority on 10x29 MT"s. Yet it still retains the same sane drivability manners of the stock converter it is. Put it in gear and I feel it go into gear solidly, step on the gas just a little and the car moves like one would expect it to without revving way up and causing a commotion. Now I know 2900 rpm stall certainly isn't 4500 rpm, but show me a 4500 rpm converter that has any kind of good street manners while running errands with Auntie Inez who keeps asking :Is this car broken?" "Your transmission is sure slipping badly...are we going to get home?: "I don't have my good walking shoes." "You should get this thing looked at" etc.
While you are at it show me a 3000 or 3500 rpm aftermarket converter that behaves like a stocker during routine low rpm around town missions. The Mrs. doesn't want to make a statement while parking the car at church choir practice. And then there is the fuel economy issue caused by all the slippage in the high stall converters. There doesn't seem to be a free lunch when it comes to performance torque converters.
