I should have guessed that! The AL block had siamesed cylinder liners in 
pairs and used the same crank. I suppose they could have offset the rod 
just a bit on the pistons, but since the engine was designed that way 
they didn't need to. Neat trick for 1930s engineers! I know the original 
design came out in 1940 or 41, but was engineered using 30s techniques. 
In fact, engineering jumped by leaps and bounds between 1941 and 1946 
due to the necessities of WWII. There really is no comparison between 
pre-war and post-war engineering, one reason the terms "pre-war" and 
"post-war" are used to refer to cars, and of course they mean WWII. 
Another reason is that civilian auto production was suspended for four 
years of the war (or was it five?), something that didn't happen (at 
least in the US) any other time. That gap makes it easy to use the war 
as a divider too. --------- Date: Mon, 22 Dec 2008 11:44:17 -0800 From:
