i know there is a difference in wheel cylinders vs the 8.8.

At least there was on mine.

Factory 7.5 was 13/16 bore vs the mustang 8.8 3/4 bore.

 

I've swapped everything to mustang parts.

 

Havent really changed much on the car, switched to hoosier qtp's which seem to work better on the street. been trying to work on the tune little by little, still on 14lbs and 17deg timing now. its been treating me well on the street taking down a 94 sn with a 306/vortech 5spd, a h/c/i gto, bbc c10 on spray (his tranny went south but it prolly wouldnt have mattered), and a fox on spray
fairmont by 1 vs fox
fairmont by a couple vs sn
fairmont by a few vs gto
