[retrac]

I reciently bought a 1987 Chevrolet C20 Chevrolet Suburban with the 454ci engine and 4.10 rear end ratio. It has The Turbo 400 Transmission, transmission cooler, oil cooler and factory towing package. I know that this is going to sound crazy but I would like to get the rear end ratio changed. I dont have a tach hooked up to it yet, so I don't know the rpm at each speed, but after 55 mph the engin rev's are so high you can't carry on a conversation or listen to the radio. I know that the rear end ratio can be reduced to something that would be better for me. This vehicle will only be occasionally used for towing a car trailer to a car show. The rest of the time it will be in general use and I would like it to be something enjoyable to drive. My questions are what ratios are available to me for this vehicle and what the cost would be to do the job? Are the parts for this age vehicle going to be difficuilt to find or are they pretty much available?
