I haven't installed everything yet to test out the combo but after looking at some gearing calculators I went with 3.90's for mine.

4l60e/ SS3800/ 28" tire/ 150-200shot/ tfs235's

with the 28" tire I wanted the extra gear, if i was staying 26" i would have just gone with 3.73s

It depends on how efficient your converter is. The 3.90s could be close, the 3.73s should be more than fine.

I went 10.50 at 130mph, with a 4400 converter and gobs of NOS. I would make sure you can lock up the converter in drive (3rd gear), and run a 4.10 gear. Then converter effiecency isnt a factor. 3.90s will be fine too. If you stick with slicks, a 4.10, if you run radials then a 3.90. Hope that helps!
