I have a 1985 S10 pickup rearend under the roadster pickup. The gear ratio appears to be somewhere around 3.08:1 . This is great for around town and highway driving, but lacks the "snap" that I would like to have when leaving a red light. I have never used a Chev rearend before, and so I am wondering A---are there more suitable ratios available as a "wrecking yard" item, and B-what all is involved with changing the gearset. This rearend is not split on the pinion side like the Ford rearends I have worked with in the past---It seems that everything must be removed on the side opposite of the pinion shaft where the bolt on cover is.
