I have 3.64 gears with 80% lock up diff from Metrix Racing. Also went with polished gears and solid mounts. I think it is perfect for my Roush 427 srtw T56 package. 6400 rpms = 65 mph 2nd gear. If I were to do it again I would consider 3.73 gears. I love the way they pull with lower gearing. Regg told me he runs 3.91 gears in his race car but his motor is a 7000rpm+ screamer. Just my 2 cents.
