t/s competitive?
(See signature)
I am looking to switch to 4.10s, add 90/10 and 50/50, solid rear control arms, 6-pt cage and torque box reinforcements. Provided I ditch the performer 5.0 and 70mm tb for a GT-40/65MM TB/GT-40 P heads with valve job and about 10.5:1 compression what could my expected ET drop be? Would it fit into the competitive E.T. range for FFW Trophy stock?
