CAMARO6 - View Single Post - TSP Stage 3 Cam (stock heads) results (C7 GS). Need heads...

I was thinking and this is simple. The engine is effectively 9% smaller or 5.6 liters. The cam is simply too large for head flow and engine size. This is causing flow stagnation and probably some reversion into the intake ports. Look the piston is only moving down the bore for 180 degrees, all the rest of the filling is because of dynamic flow. The cam is too big, engine too small to allow for this to happen. Ported heads will NOT fix this. You need to pick a cam that will work with a 5.6 street engine and this ain't it. Stage 1 is good.
