No. If anything you want the 4.5 Capaldi gear. With a shorter duration and higher rpm powerband you will want to keep the engine on a boil. A taller final drive will hurt performance.
I thought Capaldi doesn't make the gears anymore? I should really look into that then.
Jim yes I was refering to the cams that Timeless420 posted for me.

You need to find out from CAT what the power characteristics of that cam set are. You only want taller gears if you have an increase in low end torque. The cam specs you published might do that as they resemble an RV grind but if indeed the power band is raised without increasing the low end you will need to stay with stock gearing or try to find lower gears.
