How much of a .1 in the 1/4 ...deduction? With a shift kit, can I run with a 02 manuel with the same mods? I raise my rev-lim to 6250 and increased my rpms to 500 between all shifts as well.
Hey just letting you know do a search because all your doing is being a "echo". We have these gear threat by the hour on the 4.6 tech. I'm sure you'll find all the info needed after your search.

A automatic transmission with a shift kit, 4.10 gears, and a chip or dyno tune, you should be able to knock off at least .4-5 tenths will decent traction. With really good traction, like on slicks, it might be even more.
Yes, you'll run with a manual that has about the same power as you do. For the shift kit, I recommend the Jerry mod shift kit. All it requires is removing and replacing a few springs the accumulator pistons and enlarging certain holes in the valve body. For more information, go to www.tccoa.com and read up on their transmission articles for the 4r70w automatic transmission. I also highly recommend a transmission cooler at this point to keep the transmission temperatures down.
BTW, Try setting your 1-2 and 2-3 gears shifts between 5600-5800rpms. You're not making anymore power beyond these rpm levels. You can set the rev-limiter to 6,250rpms like you have so you don't run out of gear in 3rd gear at the track.
A buddy of mine had a 98 GT auto with a 4.10, shift kit,stall converter, pullies,chip, exhaust, and 315 Nittos. Not sure how fast it was in the 1/4, but it moved out damn good.
