brewnog, I don't have the specifics on these engines other than what I have given. But I don't need an accurate answer just a general answer will suffice.
Ok fellas, settle down!
Here are the specs:
5.7 L DOHC V8 32 valves (4 valves per cylinder) vs. 1.8 L SOHC inline 4 16 valves (4 valves per cylinder).
Which engine requires more torque to crank its camshaft?
Yes, I am asking you to consider the weight of the camshafts with respect to the amount of torque needed to rotate them. Heavier camshaft vs. lighter camshaft: which one requires more torque to turn?
Let us assume all things being equal other than the weight of the camshafts themselves. Is more torque required to rotate the camshaft of a large displacement V8 car engine than a small displacement inline 4 cylinder car engine?
