My 02 Z28 A4 2.73 geared car ran 13.0 at 108mph.My 03 GT 5speed ran 14.0 at 98mph.You may get out of the hole first but it will reel you in.Race in the 1/8 it will be closer.BTW 02 had a lid and cutout.The Ls1 is just quick,BUT they are quicker to fall apart.Needle bearing fellout of the rocker lost oil pressure,now sitting on used car lot. The GT is just better quality.Tell your boss to go pick on a import.
