I have a 482, 3.42 final ratio, aluminum flywheel, hydro roller cam with specs of 112 LSA 245/252, .631/.650 and a TKO w/0.82 5th gear. I drove it today and at legal freeway speeds, my car purrs along in 4th gear. I never put it into 5th gear on today's drive.

If you search the forum, then I think you'll find that the 0.82 5th is the better choice, unless your speeds get WAY, WAY above the legal limits. Too much RPM drop at least for my engine build. If I ever do get chance to change the rear gears, I'll be moving to the 3.54's which someone said is now standard with the Kikrham. I love my cam specs and would likely leave that alone. If anything, maybe one notch higher.
