The 2014+ C7 Corvette Stingray out of the box has some very high flowing heads with approximately 295 cfm.  For some of us, this is just isn't enough.  We need more flow, a more aggressive cam, and want to see over 550 naturally aspirated rear wheel HP!  

Here's what we do!  Fully CNC ported intake and exhaust ports, custom titanium intake and stainless exhaust valves, valve job, custom full radius exhaust valve job, intake and exhaust bowl blending, optional milling for increased compression ratio.



Stock Specs:
Intake port volume: 295 cc (peak stock flow 309 cfm)
Exhaust port volume: 106 cc (peak stock flow 194 cfm)
Stock Combustion Chamber Size: 60 cc
Stock intake valve size: 2.125" 96.2 grams (hollow stem)
