with your power you should be at approx 105MPH in the 1/4 mi. That is the exact mph where the 4. 10/285 tire starts to defuel with a drag comp. So you would be fine with 4. 10 in the 1/4 mi,as far as speed goes. I honestly dont think youd gain enough to make a gear swap worth it,although the 4. 10 may be slightly quicker,its not worth the $$ to swap at this point. Also if you add any power,you will be defueling slightly as you go thru the lights. I defuel at about the 1100 fr mark,from there on it doesnt pill nearly as hard. I still managed a 109. 25mph though.
If your looking to get more you could get a set of 245 tires/wheels,they look funny but the smaller diameter,and lighter weight will help at the track more than a gear swap to 4. 10 and its a lot cheaper. Id swap them b4 you go to the track,and again after.
