How can you distinguish which of these engines is which? I have one of each but from the outside there appears to be no way to tell the difference. Help please.....D

The GT80 has a black intake manifold with the word Zenoah cast into it..The cylinders have different fins on the top..The number 2850 is cast into the base of the GT74 cylinder...The inside finish of the GT80 manifold is smoother..NO other changes....
If yours are the same they are either 74s or 80s...Not one of each....

How much of a power difference is there between the GT80 and the GT74?
How much rpm difference on the same size prop?
Does an aftermarket ignition such as CH add to power?
Should have a smoother idle and easier starts.
thanks
John
