ok... i originally planned to go with 3.45's for my 9bolt. unfortunatly miles didn't get any in for whatever reason and i decided to just go ahead and get 3:73's... now i have a 89 iroc.. slightly modded (headers, no cat, free mods, elec. cutout) 350 with 700r4... i know 3.73's are gona be a little overkill at the moment. but i plan on doing a T56 swap before january hopefully and also an HSR... now 2 questions... was my thinking correct with gear selection considering my future mods? and which mod should i do first after the gears... HSR or T56... i'm leaning towards the T56 but opinions welcome

the 3.73s are gonna put you out of the powerband to soon with the stock tpi, so i would do the intake first, unless you 700r4 is on its last leg
