Just found this in the latest build story on HRM's website:
"The difference in engine displacement for the 318cid, 340cid and 360cid engines is not in the bore or stroke but in the piston height."
Now that is new to me. So the longer stroke of the 360 crankshaft (3.58") has nothing to do with the displacement? No, it is ...
"The piston in the 360cid engine is the smallest and also the lightest of the three allowing for more displacement overall."
I think I understand what the author was meaning to say... but maybe someone should proof-read stuff before they publish it.
