Corvette Performance - should I change gears

I currently run the setup in my sig with a tnt f-1 100 shot and a 26 inch tall ET street running in the 1000ft. I have to shift to forth right before crossing the 1000ft mark. My question is would I be better off going to a 4.10 gear to
be able to use all 4 gears or a taller tire to run the 1000ft in 3 gears.

If I run the 1000ft on motor the car will bog off the line. I was thinking that the 4.10s would help the bog on motor and my time will pick up but on the bottle I am curious what the 4.10s will do.

I plan on stepping up the spray once I get my ccw drag pack but still up in the air about tire size (26 or 28)

any help would be appreciated

how fast are you trapping right now....

That much power you might find 4.10's to much... You don't want to shift into 5th.

I trap 123mph

This is 1000ft

Your track is only a 1000'?

if so 4.10's sounds fine... but i don't have calc. to figure out where you will be at 1000' (trap/rpm)
