ya my car 88 mustang runs 8:20s in 8th mile with a t5 and i am putting in a c4 with shift kit and 3500 stall with z gate shifter want to no if it will run faster or will it slowdown...it has a 351 winsor and a 512 comp cam 750 holly and offinhouser..

 

Might run faster, modified C4's are pretty mean trannies.
