I've been running a 4.3 geared atlas in my buggy since birth. The gearing was really low but I went with it because at the time I was running a bone stock sbc that was factory rated at 180hp....in 1978 when it was new. It does ok as is trail riding and such but it lacks the wheel speed for serious hill climbing. I'm 90% complete on the new motor which is in the 500-550hp range so I feel pretty confident I'm going to need higher gearing in the tcase now to take advantage of all this new woopow What are some of you high hp rockwell guys running in your t cases to roast rubber on the rocks? Here's a pic of my junk with the old motor. She's wfo in 2nd gear in this pic (wouldn't pull drive with that pansy motor) and the lugs on the tires aren't even blurry.
