Notice
that all three cranks have the "notched" flange that causes most to determine
that it's from a 302.
I have personally seen two "822" cranks that came out of unmolested 1965 283 Chevrolet small blocks and have heard from numerous others who have done the same. Below is a picture showing an original "822" from a 1967 302 in the center and the 283 cranks on each side. The only visible difference is that the 302 crank has a shinier appearance - perhaps from the tuffriding process?

The
casting number on all 3 cranks is the same - 3815822
There also appears to be a second crankshaft used in the 1967 302 with
the casting number 6764. So far, I have only found these in two genuine
CE 302's, so I am unable to determine whether this was a service replacement
item only. Rich McCabe has some pictures of one of these motors on
his site at www.1967z28.com.
There are three main differences in appearance when comparing the '67 DF wheel to the '68 DF wheel. First of all, the "DF" is stamped upside down on the '67 wheel. Second, there is no date stamp at the valve stem like later Chevrolet rally wheels. The date is actually stamped on the inside and is not visible with the tire mounted. So far, I have only seen two dates used on '67 Wheels - December 1966 and March 1967. And third, the offset is different between '67 and '68 DF wheels. Below is a picture of an original paint '67 DF wheel.
Notice the
"DF" is upside down when the valve stem is placed closest to the ground.
Apparently, there is also a difference between production wheels and service replacements. The service replacements have slots that are slightly smaller than the production wheel slots. So be careful if you are trying to piece together a set of DF wheels - there are differences to be considered!!!
