I am redoing the top end of my Trans Am. I wanted to know what kinds of HP numbers and 1/4 mile times I should be expecting. Here is what I have...

95 LT1 / T-56 Car
Moroso cold air
58mm TB
Fully Ported Intake
Stage 1 ported heads (for now, I am looking at a set of 2.02's though)
CC306
CC Pro mag 1.6 RR's
CC 986-16 springs
Hooker LT's
Hooker Offroad Y-pipe w/ cutout
Hooker Cat-back
Some other little stuff

Any ideas on what to expect from both HP #'s and 1/4 mile time. I have heard about 350-375 HP depending on the tune, and about 12.5 in the 1/4. Does that hold any water?

Thanks guys,
BIZ
