3.73, 3.90 or 4.10?
Guys, I finally have a beater to drive now, and my stang sits in the garage except for weekends, or track visits. So i want more gear now, but dont want to buy different slicks.
I run a 26x8.5 m/t on 15in draglite, will i have to shift to 5th in the 1/4 with 4.10? I DONT WANT 5TH gear in the 1/4........ im looking for low.mid 1.6 60's if possible though, how about the newer 3.90 ratio?
also im putting 4cyl springs in the rear, and probaly 70/30's up front. Right now i have stock struts/springs and lak 50/50's in the back, im looking to pull the wheels just a tad on a 5k launch.  btw, i hear in an old thread you dont want 4.10's on a car unless it can pull to about 6500 rpms, or else it can slow you down, is this true?
thnx for any opinions.
