I just noticed-

Do "mild, RV" and "solid lifter cam" go together?

Does the OP have the actual specs?

I agree with the confusion about mild rv cam (typically a hydraulic set up) and solid lifter cam.
I, being a rookie in this game purchased stamped rockers/shafts/hold downs before I discovered
the solid lifters and cupped push rods in the valley pan, Duhh!
Now I have valvetrain for my next one!
After that discovery I contacted the original owner, he mentioned that it was a solid lifter cam and that I needed adjustables.
Then a few weeks later I tried to contact him again with no luck.
I agree with Echo Mike Six about identifying the cam.
Thought about placing a lifter in a few bores and measure lift with an indicator.
Will that give an idea on lift?
Where would I find numbers?
Would the cam have to come out?

I am also concerned about the old break-in lube on cam.
It is dried and funky.
I bought the engine over 3 years ago and have done nothing
but shot a little oil in cylinders and gave it a revolution or two.
I hope that wasn't a mistake?

Thanks Derek
