its already in a 53 3100 with a 5.7 sbc and a 350 trans. its a weekend driver that I want to be peppy. my 308s are good but I would like it to feel a little punchier. I looked at an rpm calculator and I believe I can live with 3.42s. they will give me more off the line and not kill my motor when I get on the highway. my question was if you guys thought a 7.5 10 bolt rear end was worth upgrading. I read up as much as I could find and for my power output and driving style I believe my current rear end IS worth a gear change. will probably be my next move.
