From: Littleton, CO USA
Car: 82 Berlinetta/57 Bel Air
Engine: L92/LQ4 (both w/4" stroke)
Transmission: 4L80E/4L80E
Axle/Gears: 12B-3.73/9"-3.89
About the only real power improvement you've made is the headers. Figure 5-10% with them, so perhaps 270 hp.

But, that intake with (what I'm assuming is) base crate motor cam and heads is going to kill your bottom end and not help you a lick in the top end (where the manifold really works). This is just a pure guess, not knowing what else you have (transmission, torque converter stall, gears, suspension, etc.), but I think you'll still be well short of your goal.
