I'm cutting consistent 1.67's w/Vig 3200, 3.23's & 10 bolt w/re-location brackets, rt. side airbag, 15x8.5" ET Drags. Will 3.73's help me out, both 60' and ET wise? '02 SS, stock H&C, stock Exh. manifolds w/Mufflex OR pipes, Dual-Dual w/Flo-tech cutout, 345 hp lid, FTRA, ASP pulley. 12.32, 110.3, 1.67 sixty. 3550 raceweight. Also, what will the 3.73's do to my mph? Thanks. WJ.

 

Forget to mention that LS1 edit has been added, also....very big gain w/it....
