Ok today i installed a new cam with a bigger lift than the last one. The old one was .620/.620 and the new is .686/.668. Well i needed to check the piston-to-valve clearance so i clayed the pistons. As i was rotating the motor over i noticed right when the rockers was getting to full lift, the pushrods were bowing a lot.
I pull the heads to make sure the valves were not hitting the the pistons, which they weren't, they had plenty of clearance. I also checked to make sure the valve springs weren't binding at full lift.
I just got new springs from AFR which are the upgraded one, which are .710 lift and 240 lbs on the seat. Also new retainers, keepers, and seals were installed. My pushrods are .080 wall thickness 1 piece design. I was thinking that maybe the 240# was to much pressure causing them to flex, but .080 wall is prettyy heavy duty.
I think i listed all the info, but im just trying to figure this out so i can get the motor back into the car. Let me know if you have any info.
Thanks a bunch guys.
