Hi, My Autotech Class has a Drag car that we over the years have built and it is time for a carb up grade its a Pontiac firebird (i know X brand) but the 383 stroker needs a bigger carb has a 750 on it now and needs an 850 or 900 DP. if anyone has one fairly cheap (we are on a tight budget) let me know and i'll talk to our instructors. Thanks DF.
