I had almost the same set up as you except for the intake manifold, MSD stuff ported heads, just the basic bolt ons and my 91 gt went 14.3 with street tires, and lucky shifting. Here is the set up i had when i got those #s:
headers, xpipe,granetelli dist., wires, smog eliminator, water pump, be cool radiator, elec. fan, 255lph fuel pump, 140 amp alt., FR driveshaft, 3.73 gears, pullies,control arms, short shifter, heavy duty clutch, 65mm throttle body, moroso in fender intake. Hope that helps a little.

It is possible to see 13's with your setup! Hope you can drive though The heads are definately your weakest point of the setup!

For sure. I just went up to 42's from 30's. Should'a done that to begin with.[:@]
