I got this in an email regarding my ebay auction for a set of SBC "X" connecting rods. The person wrote:
are they bushed ao press fit to pistons?
what is the beam width- .510 or .570?


The first line, I have no clue what he is asking.

Second line, I understand the question, but dont know the answer. Can someone tel me the beam width of stock X rods?

Thanks in advance

 

Don't know the second answer, but to the first question, he is asking if they need presson on the piston pin, or do they have copper colored bushings installed on the piston end. The bushed kind need some sore of lock to hold the pin in. Again, the second question, I don't know.

 

Stock rods have no bushings in the small end; the pistons press onto them. So unless they've been re-worked and bushings added for flaoting pins, they don't have them.

They measure about .520" wide.
