Ya Ya. Hi stall is OK for more of a track car. With the stated 3.23 gears a 3500 stall converter will always be "slipping" creating heat and poor fuel economy.
With a short duration cam, a slight bump in compression, a 4 barrel intake of 2 plane design and headers, a lot of stall is not required to make a good street driver.
Now a lockup converter can change that, but most of the older transmissions do not have that option.
