Stall and Shift RPM Question.

No argument at all about a quality converter vs a cheapo. Can a higher stall converter be made to behave on the street and have less slippage at cruise? Sure....does that mean everyone with street cars should go out and run a 4000 flash converter in 8 inch trim? No.
Why flash a 250 horse engine, with a cam that only makes power to 5000, up to 3500, just to do it? Even the reference to a a 3500 flash is subjective based on cam. said converter will flash at a certain RPM based on what cam it's working with. That same converter in another setup will behave completely different.
Am i a converter builder? NO. Do i understand that the basic operating range of a cam should affect the optimal stall speed a converter should be set up for...yes. My only point is that if your engine is falling off by 5000RPM, flashing it to 3500 when peak power is probably well below that, is pretty pointless. You've got no argument from me that a quality converter can't flash high, and behave on the street, but basic RPM range is being pretty blatantly ignored with a 3000+ flash, with a powerband of 1800-5000.

Hopefully the OP see's that a call to the techline is in order. I meant no disrespect above, I just took the said numbers to be directly offered to the OP as a suggested option, and i saw that as a cause for concern.
