Mike Jones told me they are 3 weeks out on hydraulic flat tappet big block cam orders as of last week if that helps.

I waited for over 2 months for a Jones cam, sad because he had ground one for me before and I really liked it.He said he couldn't get a core. I called LSM and had one in less than 2 weeks, and for less money. The cam out performed the Jones cam. He makes his own cores. Give him a call.

I was hearing same thing when checking with Comp and Hughes on a cam for my Magnum 5.9.
I ended up ordering a custom grind through UTAwesome Performance and to my surprise it came drop shipped from Comp in about 2.5 weeks.
Ironically, I am delayed in getting installed, so ended up not in a rush anyway.

I talked to Chuck at Bullet last week about getting a solid roller made. He told me that it would be about 6 weeks. He said they had plenty of cores but they were so busy that it would take that long. I ended up getting one from comp.

How about Clay Smith USA made?

Worth a look, I emailed Racer Brown a few days ago and haven't heard back yet. They may be more of an on the phone operation haha.
