i found a site to calculate engine rpm given r/p ratio,tranny ratio, and mph. my car has 3.73's with the tranny in 3rd(1:1) @98 mph the rpms should be around 4700 give or take.that being said i have alot of rpm left seeing i'm shifting around 5800.does this sound correct based on my calculations?? and 4.10 could help in 60ft.,et,and top end

Yeah leaving at 1600 your not gonna be snapping any Axles..
Go 4.10's, 8.5" ET Drag slicks,and get those rpms up..
Mid 1.8 60 ft times should be easy to obtain..
