340 Lifter failure, now what

Hmmmmm
Im not big on using used parts in particular flat tappet cams. I have had to many bad experiences in past decades. For the cost of cam and some gaskets I would have replaced it.
Only time and miles will tell.
I wish you the best of luck.
I drove the car to where it is sitting so I might not be a fan of potential shortcuts... I am also not wanting to pull the engine. (Yes I know I could pull rad and grill but still have a stock torque converter). I looked at each lifter that came out to make sure it had a decent rotational looking wear pattern and they all did. I was hoping to see the cam looking prettier than it does... but it is what it is...
