Oh wow good catch didt even realize that that does look off I didt check for play but I will when I get home from work iv heard of flat tapper cams being slightly off center for the lifter to be able to spin but that looks off by a lot the one lob looks almost perfectly center but the bad one looks way off Mabey that’s what caused the lifter to fail ?

So I checked the cam for movement and nothing it’s rock solid and when I look down the lifter bore it don’t look as bad as the camera is showing it it’s definitely not dead center but it’s within an 1/8 of an inch off center and they all seem that way still odd idk why it would be like that only other thing i have heard before was that some cams are off center to spin the lifters in the bore because if they were straight they wouldt spin idk tho idk how that off set would make them turn but just what iv heard before checked the push rod lengths also and everything seems to be in spec

@F150 89 Did you build the engine or did the machine shop, who assembled it?
Correct, lobes are not centered in the bore, the lifter is. This allows for the lifter to spin, I believe that lobes are not perfect shape either(to the naked eye, probably are), as this also helps to spin the lifters.
I think I asked near the beginning of this thread if the break in was done, you replied with 'NO'.
From what I know, you cam is garbage, and so are all the lifters as well. This is why people move to roller lifter/cams.
Either call your machine shop, or CompCams and get a recommended cam.

There is only one way to tell for sure.
By stopping when you did, you have saved the bottom end.
Throw another new flat tappet in there, you might not be so lucky.
What brand cam and lifters?
I'd call the manufacturer, let them know one was bad, let them know you haven't completed brake in procedure, and see what they say.

Pretty sure it will grenade itself, just like the previous one did.

wow what a ****ty machine shop told the guy speed density to so now if I go back to stock cam do I need to change valve springs because this cam recommend valve springs on summit so does that mean there upgraded ones to strong for stock set up ? Also the push rods and rockers could I reuse them

Sorry to keep blowing you guys up last question can I use this cam with speed density and can I use my stock rocker arms push rods and lifters and springs for this cam ? Or the sell a Melling stock cam should I go with that instead ? Just wana put the biggest cam possible in with out messing with the computer and from my research this is the biggest I could go just worried it’s not going to worth with the rest of the stuff I have

I just figured that was the easiest route right now unless I can get around adding the spider in the valley and drilling and tapping for it and being able to find one but I thought I heard some one say I could get a kit with out the spider that uses the connected lifters but I couldn’t find a straight answer or the kit
