I run 3.73's in my Elco. I have a TH-350 and they work great. It made a huge difference with the lower gearing. If I had to do it again I'd go even lower... 4.10's or 3.90's

It's all about what you run in the 1/4. You'd be at your top end when you cross the line and thats perfect! I'd shoot for 3.90's you have a the right idea! 8)
