Comp's XE Cams

Hwy driving? 3.23’s and no higher unless an overdrive transmission is used.
I don't disagree, however tire height can play a factor. With a 27 or 28" tire, you can easily get away with 3.55's. Additionally, a 4 speed, or lock up auto make a difference.

One thing about gearing without OD, it is a game of calculated compromises.
