May I suggest a comp cam h256?
Use new stock springs with shims if needed.

10w-30 vr1 racing oil is good.
Lucas has break in oil that is good and not too expensive.

The trashed cam was a Clay Smith 274-112. The new cam is a 264-110.
I have turned the build over to a True Professional. I seem to have more money than sense, so the only sensible thing to do is to pay a True Professional to do the sensible thing, right? Springs have not been selected yet, but I'm sure Randy [and I?] will do the sensible thing!

I'm not sure about all those assumptions, but oil pump capacity has more to do with it than the lifters or valve springs. Oil pump pressure should be a constant. I'm not sure (off the top of my head) what they offered for high-volume (not pressure) oil pumps on the L6, but that would be something to look at if you are not certain what was installed.

I know, just from history, that getting oil all the way up to the rockers was an issue requiring external tactics to get it up there, but whether that is an issue with lifters as well, I don't know. Usually by now (50 years post engine release) anything that can be known about these motors has been published - as well as any and all modifications you can and should do to make them survive any upgrades you want to throw at them.

You probably did well with going this route. I think we're all in agreement that we'd like to see more of your car out-n-about.

The ford six performance handbook covers the oiling issue..

Tricks like grinding the shank down on the headbolt that goes in the oiling passage.

If you don't have the book already I'd be looking into buying it. Classic inline sells it.

Wow a 274 cam that's a lot of cam. You plan on racing?
I'm not sure I'd run the 264 it's still a lot of cam. But you do have the C.I. head so maybe that makes it different.
