your original steel wheels are only spec'd @ 70ft/lbs, because the wheel stud is only 7/16", although i generally go 80+ (i use a limiter stick spec'd @ 80 on an air gun). without having the spec, i would use 80 on a new cragar as well. i would not go over 100.
the most important thing is that they are all the same, and that the wheel is seated. never tighten one lug to specs before the rest are at least snug. i generally go around twice, starting with low torque, and increasing until the 5th is at spec. then backwards or restart (in a star, of course) tightening the other 4. and recheck alloy wheels after 25-50 miles. if any have loosened, rinse and repeat.
i wish i could say "until they feel right", but those results may vary. it is the method i have used on any alloy wheel i have put on my car, and they all end up being about 80-90. i havent had one come off yet.
