Brent Mills Hi Couple of questions? If the edges of the pushrods are broken off you have the wrong size ball for the rocker. I would buy a set of Smith brothers push rods with the correct ends. Are the rockers chewed up under buy the adjuster screw causing a binding of the pushrod to the rocker. If this happens it will push the pushrod end out of the center of the rocker adjuster and possibably cause the valve to hit the piston and hit the valve, causing the pushrod to bend or break. If you know someone with a bore scope look in that cylinder and see if any contact has happened. I donot know of anyother way a pushrod can break. Are the ends of the pushrods blue, burnt , lack of
oil to lube the parts. Makebe there is a oiling problem with the rocker shaft oiling holes to #4. Grind all of your rocker by the bodys between the adjuster hole and the rocker body for more lift and clearance for the pushrods full movement without binding on the body of the rocker. What where you doing when the pushrod broke?? cruising, WOT, idleing, hear any change in the motor just before it broke. Do you have limiters in the heads for
oil control? I would look at the size of the holes. .080-.090 is what most people are running. I KNOW SOME PEOPLE ARE RUNNING ALOT SMALLER WITH NO PROBLEMS.
Hope this points you in the right direction. I would call George Anderson at Gessford and see if he can help. He has alot of FE knowledge and answers Rick Lake
