Re: Highway Speeds

71 swb
355 heads/cam
700R4 w/ 2200rpm converter
3.73
255/60/15 (28"-ish)
22-2300 RPM at 70mph locked. 2500-2600 unlocked.

This is pretty much the ideal gearing in my opinion, although I prefer to cruise at 65mph. Every truck has an ideal cruising speed, mine is governed by road and wind noise, vibrations, etc.
