Stock49, Here's a link to what some might call the ultimate boxer engine. The Porsche 917, 12 cyl, 300 ci, turbo charged, 454 Can Am killer.
http://www.pbase.com/917carl/917_12_cyl_engine I'm not sure of all the particulars, in fact I was thinking the 917 was an 8 cyl.. From looking at the pics, it appears that 2 cyls are on the same journal, one piston is at TDC and the other is BDC. The motor doesn't look that much longer than a 292.
I saw the 917s at Laguna Seca. You'd hear the big McLaren 454s come thundering up the hill, and then the 917 would top the hill and scream by with McLarens following.
