I just went with an Edge 3000 rpm stall, and picked up 4 full tenths in the 1/4 mile. I'm a bracket racer, so I have extensive records of how my car performs in every weather condition, so you can take that 4 tenths to the bank. I also got the high stall problem after 4 passes down the track, but that should be fixed now, just waiting for Saturday to try it out. You will notice a difference in driveability, but you'll get used to it. IMO, 2800-3000 is perfect for stock motored cars. Anything less, and you'll be disappointed. Call Andre at Edge if you have any questions.

Stock our cars make lots of torque down low. Like mentioned above - most manufacturers over-rate their converters and they actually stall sooner than advertised. However, that said - a 3600 converter would be ridiculous on a stock car as your are losing some of your power band. To a degree your engine builder is right - if you have a converter with a true stall speed of 3200 that is going to be sort of a waste and you are cutting out some of your power band. However, the converter will generally not stall at as high a speed as is advertised.

That said, OBD1 cars (excluding '93 which does not have the 4l60-e) sometimes have trouble with converters that stall in the 3000+ range. Tuners can supposedly fix this - but custom tuning is an added expense. I would just go for a 2800 converter personally. Wish i had gone with a 2800 on my car
