340 6 pack pushrod diameter?

The length measurement can be tricky...

Most of us would measure from end to end to get the length... When we built Eddie's engine we found that the manufacturers measure the length from the tip of the ball end to the bottom of the cup on the adjustable lifter pushrods...

So be careful when you talk the length of a pushrod and try to compare it to 'manufacturer specs', there is a difference...

It would be safer to actually tell how you are measuring the pushrods when you talk about the length...
