Should I look at link bar lifters? Saw some ferraras with good reviews. Or just stick with the johnson 2110s?

The benefit of lighter parts on the valve side is control. Less mass is easier to control. If you increase mass on the valve side, you must increase spring pressure, which means you need beefier lifters and pushrods. So your focus on mass reduction in the valvetrain really just needs to be on the valve side
You do not need link bars until you reach a certain lift. There are trays in the factory engine that hold the lifters in the proper orientation. So as long as you keep your cam lift below .650, which is what your cam options are, johnson 2110 is a great choice.

Heavier valve train parts only make the motor lazier if they are on the valve side. On the lifter side it is usually a benefit.

The btr spring I am comparing the PsI to is the btr platinum ls spring with optional Ti retainers.
I have btr springs in my 5.4 and they have a good rep in the Mod world is why I ask.

Nice choices. Spring life largely depends on cam and springs chosen. An aggressive street can with normal springs will typically last more than 10k miles but they say to at least pull one every 10k and check it.

Yall promise that size of cam will have the idle I want? Watching videos of the titan king and it Chops.
I assume something like the titan 3 would be a less aggressive choice. Still good idea to check every other oil change though huh? I guess its a much easier deal on an ls than a mod. Have to pull the whole front cover to check springs on those.

Again it's about what you want. The Titan 3 is a good compromise, easier on valvetrain with a lower power and for a streetcar, and will still chop which can also be made more rowdy with the tune. If you want just plain nasty and don't mind revving it or having worse street manner, go King Titan.

The cam will do it for real? Also its not crappy. Its just a function of how the cam works. These motors arent vvt. Cant have your cake and eat it too. Its not like im getting a "ghost cam" tune on a coyote here.

If the tuner needs to make it lope or chop, it's not that big a cam. A lope or chop is an intermittent miss. If it can be tuned out, it is no longer running crappy. But that is your choice.

It's up to you if you need the boy racer sound. You're losing power and efficiency by doing so, which I think defeats the purpose of building performance. But whatever..

Thing is by using the adaptive spark. It will idle choppy. It once you clear 1.2% throttle it jumps to the main tables. Then it runs as smooth as the cam allows.
What exhaust are you running on your Vette. That has a whole lot to do with the sound you're looking for. I have Kooks 1.875" long tubes along with non catted Z06/ZR1 mid pipes and ZR1 cans. Even with my itty bitty cam, it sounds good with the flaps closed and sounds more than a little nasty with the flaps open. At 7000rpm, it will wake the dead.

So
Titan 3 cam.
Johnson 2110 lifters
3/8 pushrods of tbd length (brand? Material? Cm okay?)
Springs? (dual, single? Psi? Btr platinums?)
Ti retainers (does brand matter here? Probably would just go with same brand as the springs if possible.)
Almost there.
