Bent Pushrods on a rebuilt 318

Ok... looking at the vid...you will have to start over ... hate to say that.
Check everything good.. cam, lifters, valve guides, valve seals, even check the springs. Double check everything.. you don't want to do it all over again.
Was cam degreed?
What I recommend doing is running adjustable roller rockers. This is only a recommendation but if you're going to twist the engine any significant RPM this is what I suggest. I had a 273 with a smallish cam and was running down the interstate when all of a sudden my engine started running poorly. Got it home and removed the valve covers. Push rod had punched through the stamped steel rocker. I knew then I was NOT a fan of stamped rockers. Maybe for 100% stock cam but not for any higher lift cam. Replaced that rocker and drove if for awhile until I installed a 360.

IMM Engines is building me 408 stroker engine and I'm not going to use the stock pedestal rockers (magnum)... I'm going roller rockers. LOL... I don't like pedestal type rockers either.
First and foremost contact Mike at B3racing. Mike is a very nice guy and he went out of his way on answering my questions. He's a member on here and he sold me a set of PRW roller rockers. They aren't the best in the world but not the worst either. No needle bearing is the ones I use. He also sold me a geometry kit in which that set the rocker tips dead center of the valves with a narrow rub pattern. It does make a difference.

Make sure you got the shafts turned correctly this time.... lol. When I have the shafts bare in hand I hold them up and look at the oiling holes and make sure they are pointed down the furtherest they can go. I might be a crazy but even though the holes are pointed down the holes are not drilled center of the shafts. After I have confirmed that I take a grinder wheel and zip a very small notch in the top of the rocker shaft which is facing forward of the engine. That way I know that I will not mistakenly turn them backwards.
Keep us posted .. I don't mind helping.
