Many years ago I was within earshot of several young farm workers eating lunch together and discussing their car engines when one of them said "engines don't last very long because of that little "thing" that was put into the engine when it was built". A little "thing"? Huh?
When ignorant people don't know why things happen they come up with astonishing reasons to explain those things and what I heard that day was just one example of how C3 myths get started. And once a myth gets started and repeated over and over thru the years the myth becomes fact.
Can any of you think of C3 myths that have circulated thru the years?

Over 50 years ago I remember hearing stories about some guy that invented a carburetor that got 50 MPG. The story goes that GM bought it and shelved it.
As I have reconditioned at least 1000 small block cylinder heads in my lifetime I would bet I know a LOT more about them than you'll ever know. The only small block heads that ever got the push rod guide plates were the 2.02" X 1.60" heads because they used a wider 1-7/8" valve spacing which is 1/8" wider than the 1-3/4" lifter spacing. You see, you can't put a 2.02" valve next to a 1.60" valve with the standard 1-3/4" spacing because they'd clobber each other. The #186 casting number head you see in the picture does NOT have the larger 2.02" X 1.60" valves but rather the smaller 1.93" X 1.5" valves because the 2.02" X 1.60" valves REQUIRED guide plates because of their 1/8" wider spacing. Sorry but you're dead wrong.
