What lifter would be the best choice?
Everything that is in my sig I have. The night I posted this thread I was about to place an order through Tick for the BTR lifters, but I thought I should get a few opinions first between the lifter choices I listed. And yes I am sure I have the SNS stage 3.
I'm running the Morel 5206s, which are link bars. I did a lot of research before going with them, and I have been totally satisfied with them in every aspect. I precisely assembled all of my valve train, using all high quality components and the results are a very quiet valve train, and extremely stable up top. They cost some money but they are worth the insurance and performance/safety they provide.
Even the Morel 5290s are not much of an upgrade IMO. They are essentially the Eaton OE design with better materials, tolerances, and a captured link-bar (which is a good upgrade).
Going to the Morel 5206 provides the larger wheel and much better materials/tolerances.
But for that price, I went with the Johnsons (ST2126LSR). They are .058" short travel with axle oiling. They have a stock sized axle, but are designed to withstand 900lbs of open pressure and can actually withstand more spring pressure than Morels with the bigger wheel. I'll have to find the literature on it, but I believe it was due to the heavier duty axle retaining mechanism Johnson employs with the OE sized wheel.
Pretty much. All of them are Eaton type lifters. The Comp 850s, etc, etc.

The only thing the same is the wheel diameter and that they fit in an LS/SBC engine.
No they are not the same as the LS7, not even close. I have taken both apart and inspected. The LS7 uses a check ball in the bottom of the plunger, the BTR uses a spring loaded check disc. The plunger in the BTR is larger diameter which allows more oil in the lifter, so the lifter body itself is slightly thinner. Yes the tolerances are tighter between the plunger and the body. They are cheap because Brain Tooley is a hell of nice guy.

Like the title says. I am looking at changing out the LS7 lifters that I currently have since I'm swapping cams again. I was looking at the BTR SLR lifters, Comp 850 lifters, Morel 5290 lifters, Lunati 72332. I know there are better lifters out there but I think any of these would be a step up from the OEM lifters. I will be running the cam and springs in my sig with these. I will be shifting around 6700-6800rpm. Any help/advice would be much appreciated.
