2 sep colder plugs for a 125 gapped at .035 (ngk TR 7's are good)


ignition upgades, bigger fuel pump,


that should be good-- if you have a distributor retard th timing yourself, if not get a chip or flip chip with the right amount of retard...


should be around 4* for a 125....

always run 93 or better octane on the juice....

besides that do everyting as you normally would on a stang, intake exhaust gear...


also i dunno about the v-6 trannys, they might not like a 125 shot too well....
