Hey mon Deb,
This is the first mention of a spinning/rotating push rod that I've seen here, and I just wanted to say this about that: The spinning of the push rod is the result of the spinning of the lifter (solid, maybe hydraulic, but NOT a roller tappet). The spin of the lifter is imparted by the lobe on the camshaft not being ground absolutely square, which means that the lifter (at least this is true of a "solid" lifter) is contacting the cam only on one edge of the lobe.
I have the set of lifters that came out of the 3.14 in 1989, and the surface of the lifter that contacted the cam has a distinctive pattern worn into it. I've also looked at the cam that came out of 3.14 at the same time, and it has a distinct "non-right angle" slope to the cam lobe, and it slants down from the back of the lobe, which gives the cam the tendency to be held in an "in" position.

I remember putting something against the pushrod as it went up and down to test that theory but now i can't remember what the heck the results of that little experiment was. LOL

I know what you mean. I one time put all the components for a small nuclear device together, but that was some time ago, and I can't remember what happened when I set it off.
Hope you are well.
