push rod ?

The 2nd paragraph in post#62 says you were gonna do the test with current parts, which I assumed were the 7.25s.
So,yeah Im confused. Did you perform this test with a 7.5 inch, small end, rod. And are now going to order the rest as 7.5s?
Or are the 7.25s the right ones? In which case the big-balled ones have to be discarded.
