So short of a link bar lifter, what Johnson hydraulic lifter would you use if you are shifting at over 7k? Preferably something that does not require new pushrods.

The only way to correctly answer this question is with more questions. Mainly - what's the complete combination? Knowing the cam you're going to run and what the rest of the combination is (intake manifold, cylinder head, transmission type, any power adder) will inform what the car is going to see for RPM and what amount of valve-spring pressure it will need. Those two key pieces of info are closely related, and in turn will inform what you should consider for lifters.
In general, most street driven cammed LS setups are going to thrive with a Chevy Performance - Racing lifter, also referred to as the GMPP or Caddy lifter (PN 88958689). These are a drop in replacement for an OEM LS7 lifter, and have a few improvements - mainly higher overall material quality, tighter internal tolerances, and a better ceramic check ball mechanism. They usually retail about $100 over genuine LS7 lifters, and are well worth the extra cost. The lifter is by far the most common failure point in the valve-train, if not of all the internal components on an LS engine - and so it makes sense to invest a little extra there. Your lifter options are basically as follows:
There are of course other options out there, but that should give you some things to think about in choosing lifters.

Would you consider Comp Cams Evolution hydraulic roller rockers or would you stick with GM Performance. The cam in the my 2011 Camaro LS3 manual transmission with 3.91 gears is a GPI LS3 SS4 No Fly Cut. Stock heads and block.

One other thing that I've never seen a straight answer on is if the Delphi LS7 lifter is in fact identical to the GM LS7 lifter, or is it ebay junk or somewhere in between.

I had not heard of a Comp Cams Evolution Roller Rocker, so I went looking and quickly realized you meant lifter - which makes a lot more sense with the ongoing conversation. I can't say that we've used these, and I don't know nor have heard much about them. At $600/set, they are going to have to be a good lifter to make sense to most budgets. I'm all for tried and true unless it doesn't do something you want, and I think the Chevy Performance Racing (88958689) would be the go-to for your application.

Agreed, and Andrew is also the person that pushed me over the edge to go with GPI over the others. These guys know there shit. I was impressed with his honesty on which parts I need for the cam swap on my ultra low mile SS. He is in the business of selling parts, but he was honest in what he would change and wouldn’t in my car given my circumstances rather than telling me I need two of everything regardless of miles and circumstances. These guys are THE BEST.
