Should I do 4.10 gears with LT4 kit (heads, cam, intake) making 425hp?

I was just wondering if it would make much difference putting 4.10`s in this car. I know gears are really supposed to "wake up" stock LT1`s, but what about an LT1 with the LT4 kit with cam, heads, rockers, and intake. It was dynoed at 360hp at the wheels, which I am guessing will get me in the low twelves. I would like to get into the 11`s, but I am worried I might tach out in 4th. Thanks.

Auto or 6 speed? I loved my 4.10's in my auto, until I did my CC305/ported head swap. At 112 MPH trap speed with the 4.10's, I'm on my 6000 RPM shift lite about 75 ft. before the finish line in 3rd gear...I went a 12.0 shifting into 4th gear.
As you can see from my sig, a 3.73 swap is in the works.
