Well I guess I was a bit hasty in my bio, I did a 3rd memeber swap up front with 4.56 ratio, but have not changed the back, I have been wating for my detriot electrac to come in, which it finally has, I will have the new gears installed by this weekend, and will be able to give you an idea of their helpfulness. I too have had big time power problems at highway speeds, and also have problems accelerating.

I talked with Joe D. a while back, and he talked me out of an engine swap, he said that the 4.56 change is like night and day. So I will be anxious to see what happens
