4.30 gear and 29.0 tire and 67-7000 r's puts you at 135-140 mph. I seriously doubt you have the engine for that. 135mph in the 1/4 is equivalent to a 9.80et..........In my opinion you'll need a shorter tire and more gear............or a throttle stop....lol.
To run 11.5 which should be around 116mph and to clear the traps at 67-7000 you need a 5.13 gear with the 29's and a 4.56 with a 26.0" tire.
Also, with the 29" tire and 4.30 gear at 116.0mph with a little conv slip you would go thru at 59-6000 rpm's.
My advice is to run it as is and get some data (incremental numbers and mph) and decide what you need after that.
