This winter I am planning on puling out the motor and checking everything out. While it is out I am thinking about pulling an intake swap. It is a 355 with twin 62mm turbos on it. I am running 10:1 compression and around 10psi of boost. I currently am running a HSR with an Accel/Lingenfelter 1000cfm throttlebody. I am pleased with the setup but I would like to see if switching to a single plane intake with a 1550 throttle body would make anymore power. What do you guys think?

Here are my cam specs:
1987-1998 SR/HR ROLLER
DURATION @ .050 INTAKE 230 ROCKER ARM RATIO
DURATION @ .050 EXHAUST 236 INTAKE 1.50
VALVE LIFT INTAKE .510
VALVE LIFT EXHAUST .520
LOBE SEPARATION 114.0
INTAKE C/L 110.0
