I need to know about how much horse power is needed to power either a 6 or 8 cly gas engins valve train.Both Intake and Exhaust valves. Say 4 valves per cly. I need this as a percent.
What for? lossen the valve springs to save HP to the valve train, but suffer HP loss when valves "float". It's a trail and error game. Eventually you could run enough combinations to write your own equation taking into account springs, cam lift, rpm, CR, fuel....
