The gears are way too low. get some 4.10's
ATI makes very good converters for both street and race.
The 3.08's will cause you to be "on the converter" way too long and create excessive converter heat. Its a mismatch for a high stall converter.
Not to mention the acceleration will be lame.
Get some 4.10's or 4.30's and then get a 10" 3500 stall for max street strip performance.
