I intend on installing a Mach/Maruarder/Aviator motor in my 99 GT next spring and I was curious as to what kinda of ET's and dyno numbers Mach1 guys are turning out on the bottle. My GT has a Zex Wet kit jetted for 100hp and 4.10's. I will probably install Bassani mid length headers at the time of the motor swap to go with my Bassani Xpipe and Magnaflow catback. Im hoping that'd I could squeeze 11's outta this combo with the 100 shot and drag radials.
