Wow, for a 2nd I thought someone put my GTA up for sale and didn't tell me! Aside from the wheels, its pretty much the same thing as my car. LT1 / T56 swap. Except, thats a TransAm and not a GTA. GTA = no fender vents, body color badges on nose, fender, sail panels. Gold "Pontiac" lettering on DS headlight bezel, Gold "Flaming bird" emblem on center section of tail light.
Then again, once the T56 and LT1 are in there, the "GTA" doesn't really matter since its got a 4th gen interior which is leaps and bounds better than a thirdgen interior.
As for fuel economy? I'm averaging 21-23mpg combo, and I got 32mpg on the 160 mile trip up to Road America cruising in 6th without cruise control.
ET / Trap would be about low 13's @ 103-105mph. B-body LT1s will trap lower, about 103mph due to the less aggressive camshaft (Dur. 191/196 @ .050" lift. 111* LSA) Tiny cam.
mods to my LT1 are CAI, Tune, Exhaust.
