This engine is a bit of an anomaly in that it looks for all the world 
like a pair of boxer-6 engines tied together.  It has a gear train in 
the middle, where the "two engines" would be connected... single 
crankcase but it looks as if it shared a heritage with a pair of 
6's.   It sure made power though, been fascinated by this thing ever 
since I caught the movie "LeMans" on cable about 25 years ago (never 
saw it in theaters since I was wearing OD green and crouching in the 
bushes when it originally ran through theaters) that featured Steve 
McQueen's Porsche 917 as the camera car that filmed some of the race scenes.

Interestingly enough, the *Camera Car* itself finished in the top-ten 
if I recall.   The cooling fan on this thing doesn't look like much 
of anything special, either in size or configuration, yet it managed 
to cool an engine that in some variations made nearly 1000hp.

If you get a chance sometime, check out "LeMans".  It's probably one 
of the best race movies ever made, if not THE best.   The early '70s 
was, for this kind of racing, kinda like a swan song era... before 
politics, electronics, space-age science, and enormous expense took 
over things.   Kinda like baseball's documentary film, "When It Was A 
Game", LeMans pretty much documents a time when racing was simpler 
and more pure, a bygone era that's unlikely to ever return.   The 
Porsche 917 was one of the champions of that era.
