I have a CJ7 with a rebuilt 4.2, weber carb, beefed up ignition- a very strong runner considering I live at 10,000 feet with a carb. I have a T-5 and my axles are geared at 3.54 with 32" tires. I don't have alot of low end torque; I have to ride the clutch a little when starting on a hill, I can do almost 50mph in third gear and I've never shifted into fifth. I considered gearing to 4.10, but alot of local shops think this is pretty tall for my set-up. I'd rather not spend the money on re-gearing. I've had guys suggest a tranny with lower gearing or cam replacement. Apparently this engine was rebuilt at a speed shop before I bought it. How can I tell (can I tell?) if an RV cam may help my situation. Any thoughts out there?
