For an LS2 GTO with long tube headers, CAI (cough, cough), and aftermarket catback where do you think the following mods will put the performance?
Cam
Futral Motorsports FM-F13-112-HIGHLIFT
FMS Custom Grind Camshaft - 230"/232" .642"/.612" 112LSA - aggressive profile with a 2500-6800 RPM range, rough idle
Heads
Trick Flow 225cc Heads Prepared by Total Engine Airflow (TEA)
During the development stage, Trick Flow engineers determined that the valve angles needed to change from 15* to 13.5*. This change decreased valve shrouding,increased mid-lift airflow,and increased rocker arm-to-valve cover clearance.Testing also proved that relocating the spark plug position in the combustion chamber further enhanced combustion along with mid lift airflow and improved the integrity of the casting in the chamber area. Trick Flow also added additional material to the decks (.600") and to the rocker arm mounting pads to improve high rpm valve train stability.
Assembled heads come equipped stainless steel intake and exhaust valve,with 1.300" "dual gold" valve springs for lifts up to .650", viton seals,machined spring locators,7 degree titanium retainers and machined steellocks.
One last important feature of this 13.5* head design is the valve drop.This head features a .155" valve drop on the intake, a stock 5.7 head with 2.00" valves has around .150". What this means is you can run this head on stock pistons with large camshafts and still have more piston to valve clearance than a stock head and also more compression.
The 225 LS-2 heads feature all of the same design advantages of the LS-1 with the addition of a 4.00" bore combustion chamber,2.055" intake valve, 225cc intake runner,and a 67cc combustion chamber volume.
Intake
