i have a 95 mustang gt auto.... right now it has a shift kit, cai, pullies, msd, bbk o/rx pipe, and flowmaster 40s.... my code on the door says i am running 3.08 or 3.27, i cant remember which..... but the best i have been able to run is 15.5 in the 1/4... if i go with 4.10 gears, about how much of a gain in my 1/4 can i expect??? any hep will be greatly appreciated..
