My buddy has a '92 GT.....
Iron gt-40's mild port and valve job, stock gt-40 intake, 1.72 r.r's, south sides, 50/50's, 125 shot, 3.73's,,,and some little stuff.
He goes 12.40's on the motor, and 11.40's on the spray.
I think he went from about 13.20 to 12.60 when he did his head change.
When i say "mild" port job that it what i mean.....Alternative in MI, just cleaned up the exhaust side, decked them to get him about 10:1, and valve job(probably $150-$200 total)

4.10's,long tubes & 75 shot...Goes 12.50's
