I have a 4.11 Columbia in my other car and am thinking of going up a step in the gear ratio for this one. Looking for your actual experience on this setup. Thanks!

Just a comment to consider in your thinking .. Flywheel should be a factor as well - I have a strong 284cu (supercharged) with 4:11 and Columbia with an aluminum flywheel. I my case the 4:11 is great for around town performance and easy launch with the benefit of the 2:97:1 high for lower (28.5% reduction) in RPM at 65mph. I am happy with this combo with the lighter flywheel.
