Man they that stinks. I didn’t like the look of the shine I could see in that one picture. Did you have to crank this engine long on first start up and did you preprime the oiling system before trying to start it?

#6 exhaust lifter face is slightly concave but no marks on it. That's like you girlfriend being slightly pregnant...Cam and lifter time...I didnt see what your cam break in process was but its important to break in the cam properly.

It doesn’t sound like it had much run time on the motor. If so, and looking at the lifter, I’d say it started to fail right off the bat.
The cam is a decent match for the combo, other than perhaps if the converter really only flashed to 3000, it would be a little lower than what I’d consider optimum for a cam that size.
FWIW, for the last several years I’ve used Driven “BR” break in oil exclusively.

Ya go with a roller cam because nothing ever goes wrong with them. Approximately fifty 6.50-6.60’s runs on a new set of Comp roller lifters before the link bar broke on my sons 360 trashing the whole engine.

You're comparing 50 passes with not even making it past the break in? Are you for real? S/F...Ken M

If the op has a lathe, or a friend that has one........ put the cam in it and indicate across the base circle of the lobes from front to rear. There should be roughly .0015-.0020 taper on the lobe.
If the taper is good, there should have been good lifter rotation.
The cam I posted a pic of with the lobe gone had .0020 taper...... and it was nitrided...... and was using EDM lifters. Owner was running regular SM rated oil, no additive. It was also ground using .904 lobes. The one lobe was gone, another one was pretty bad, two others were starting to fail. That had one summer of use.
Replaced cam with something a little smoother, non-.904 lobes, ran it with inner springs removed for a longer period of time........ and continued to use Driven oil after break in. It also was nitrided, and is using EDM lifters. It lasted this past summer and seems to be surviving.

S/F...Ken M Ya I’m for real because I know and have seen the most cam failures happen because of the oil used, the builder missing something during the build, or improper start up. Most are to lazy to pull the inner springs or can’t set the timing close enough to get it up and running without cranking the hell out of it. Some don’t even start out with a fully charged battery. Some start with two year old fuel. Lots of reasons to blame the cam. Lol.
