I have developed a bad lifter in my 340 A66 Challenger. The engine only has 10K on it. Should I do the entire cam or take a chance with just replacing the lifter.
Let me guess, Comp Cams….

No, actually mopar purple p4452761
Yes I wish I knew why it went bad, have not done a visual inspection yet but most people around here say to be safe replace both. It was the mopar cam p4452761.It depends why the lifter went bad if the bottom looks OK & it just will not hold pressure then a new lifter should be fine . if there are any signs that the lifter is not rotating or wear on the bottom which you can check with a straight edge , then the cam probably caused the problem & I would replace everything .
It also depends what cam is in there & if it is worth putting a better cam such as a Lunati VooDoo

Bummer!No, actually mopar purple p4452761
Ok bummer it went bad or bummer on my choice of camsBummer!
Yea, theres always a back story.lol. Had it rebuilt about 30 years ago and was bored 30 over. Shop did a bad job so had it done again and they had to do another 10 over. Right now it has 10k on the current build, dont drive it too much,Only 10 thousand miles on the engine. Is there a backstory to this engine you haven't told us ? How stock is it and how do you drive it ?

I know right!Bummer it went bad.
But not surprising.About three weeks ago I had a lifter collapse during break-in on a 340 CI engine. All Comp Cams valve train components. Pretty disappointing!
