mod motors are especially responsive to :
exhaust (h pipe) stock manifolds are "OK"
mass air is a lil' restrictive .... stock TB is a 65mm so it is pretty good form the start
and timing.... they like a good 14- 15*
alot of people have done just pullies , h pipe, timing adj and mass air and got some really good gains...... look on corral
anyhing that you can do to the mustang 2v you can pretty much do to the vic's and t birds......
