So... I have a 427 side-oiler (aftermarket block) in my Cobra and the roller on the roller lifter seems to have come apart and jammed in the bore which caused the piston to smack the valve and drove the adjuster through the rocker. It did not bend the pushrod surprisingly and it looks like I might be able to punch the lifter out the bottom end. I will have to cut the link bar and the tab on the lifter though. Anyone else have any experience on this? After this, I'm going to a solid cam, if the bore is okay(ish) can i run a solid lifter in it or do I need to get the lifter bore bushed. I haven't pulled the motor yet cause I'm afraid of what I may find...plus I've been extremely busy at work.
