At what RPM does your stock cam stop pulling,and start flattening out. My engine starts flattening out around 5500, is that normal? Just wondering if it's the valve springs or the stock cam.
TIA

Actually, the HP peak is around 4600-4800 RPM for a stock cam, stock head car according to the dyno. Kinda makes you wonder if shifting earlier might make you go faster......
