- Oddly enough, I had the same power loss/rough engine thing just happen, and it was the fuel filter. However, that was just a warmup for things to come... Last week I heard a loud top end knock, which

- well if the valves floated it could cause that or if the lash was not properly set. do a compression check on that cylinder. i doubt you could bend a pushrod and not hurt something else. also if the

- You need to use hardened pushrods if you use guideplates. Also, stock rocker arms may not have enough clearance for your high lift cam. The third possibility is there is not enough clearance for the

- Early 260, and 289 (pre '68, I think.) used a ball and socket type rocker arm and the arm was prevented from moving by narrow push rod holes in the head. These holes act as sort of a guide plate. Lat

- This sounds bad as pushrod failure usually does not happen unless there is contact with the valve to piston or some other physical contact or bind. If this contact did happen and you replace the pus

- Arnie, do you have screw in or pressed in rocker arm studs. If pressed in, and high stress, it may pull the stud out far enough to loosen the rocker arm, and the push rod comes out of its location. T

- Hi Arnie, It sounds like you have the correct head for non-rail type rocker arms. I also bent a push rod that was caused by excessive clearance. I was able to replace the pushrod with no other damage

- I recently had my heads apart. I have a 1964 built 260 with non rail type rocker arms. On my cylinder heads the hole that the pushrod passes through is NOT round, but is a machined hole that is very

- My suggestion would be to ensure that the studs are not pulling out of the head. Put a straight end along all of the studs. I assume you have a stock 260 head with the correct adjustable rockers tha
