I have a 1991 Camaro RS that has a motor swap. It has a 6.6L 400 small block chevy, tbi injection, gear drive timing, behind the 400sbc is a Borg Warner T5 5-speed, with a Eaton detroit trutrac locker 7.5 inch rear end. I have some money to spend on my car, and I have a few ideas, which will be listed below, but I would like some input. Im shooting for the 400-500hp to the wheels range. I have had the car dyno'd and its making 210hp, 325tq to the wheels, 260hp, 410tq to the crank. The car runs 9.2 on the 1/8th mile at 79-81mph.

Idea #1:
Holley 750 Double pumper Carb, Torker II intake, MSD HEI Distributor, aggressive cam (not sure what cam specifically yet), holley red fuel pump, msg ignition wires.

Idea #2
Holley sniper EFI, Torker II manifold, MSD distributor, aggressive cam, Blue Print Engines Muscle Series Cylinder Heads (Aluminum, 195cc Intake Runner, Straight Plug, 2.020/1.600 in. Valve)

I know the transmission will be pushing its limits at this point, but I plan to do a T56 swap after my T5 goes. I'm also looking to switch to a ford 9" rear end with 4.55 gears (so I can run full slicks).
I also will be upgrading the suspension and getting subframe connectors, and a strut brace.
