456 gears
I think with your mods and the 150 shot you would run out of gear on a 26inch tire. On a 28inch tire you might be close but I would say go with 4.10s if you want a track only gear.

26" Tire would max out 3rd @ 107mph, OD @ 153mph
28" Tire would max out 3rd @ 115mph, OD @ 164mph
Both calculated with 6300rpm rev limit set.
I would stick with the 3.73s and not bother entering into OD (reworked trans needed for WOT OD shift) and then utilize maxing out 3rd at 131mph w/ 26" and 141mph w/ 28".

Yea, +2 on the tune idea. And 4.56's would make first gear basically non existent with that stall too. 4.10 would be my high number in that equation.
Before and after the tune is night and day. With all that work, it is an absolute must.
