Do not use a 3000 stall no direct drive converter with 3.27 gears. Your trans will certainly overheat and you will hate it. If you use the direct drive with that you will hate the shifts and break the stock shaft. Go with no more than a good 2200 stall or you will have driveability issues or you need to change gears. If you are dead set on a 3000 stall converter you'll need 4.10's or 4.30's to keep it in its operational range. Hughes is a crock they over rate and overcharge everything. For an aod edge builds a decent unit at a low price or if you want to contact me I'll see what I can get done for you because i know people.
