it says 1/4 mile at 12.21 and 110 miles an hour
at 3860 pounds for a ss manual at 422 hp it should run.

1/8 7.70 at 88.24 mph.

i put it in the 0-60 calculator but it says 3.56 although id be happy with that i know the 0-60 is wrong
a dif site says 4.41

The reason the numbers are not coming out right is that the car won't shift 6 times in the 1/4 (at least I think that is what you meant). Actually, the manual car will shift into second just before 60 (about 55), and the auto shifts into third at 66, which is why the auto runs much better to 60mph. And in the quarter the manual uses third gear through the 1/4 mile (to 114 mph), while the auto shifts into 4th gear at about 102. This is why the auto has a slight edge, it is geared more aggressively for acceleration than the manual. Don't ask me why they did that, I would think you could dedicate 4 gears to the 1/4 mile run with a 6 speed manual tranny, and still have plenty of room for overdrive, but oh well. They really geared this thing to keep revs low to help fuel economy I suppose.

As for the calculator, the manual car will shift only twice (1-2, 2-3) in the 1/4.

I guess 4.5 auto, 4.8 manual
12.9 auto, 13.0 manual, both at 108 mph
