1st Sticky at top of this section as proven by Thunderstruck & Darth
Cam Motion LLSR W/ Stock Rockers (I would do bushing upgrade perhaps shaft also),
Quality lifters, 11/32 minimum PR, lash caps & shims with OCD attention to detail.
Less money but more time for set up.
My .02
I have pedestal mount T&D adjustable full rollers held into place by 10mm bolts in the 01 and I'm not sure if I'd run them with a solid setup spinning that high and I certainly know how to find out but don't want to. I find myself in the middle with parts as I went for the dragonslayer crank but only Compstar rods when I know that's one place you don't go cheap. Now I'm not making 1000fwhp and I don't have a bottle on it yet either but if I'm turbocharging I'm thinking new connecting rods. I love NA but I'd be lying if I didn't envy those out there running with forced induction.
Compstar rods laugh at 1000whp, they are perfectly fine at 1200+ as well.
I'm not exactly loaded with lots of real world experience, but this is one I've actually witnessed as my friend has an 8300 rpm LS1 that runs 30 minute track sessions with stock rockers and he's been doing it for years.
Exactly, I've seen way more broken "fancy" aftermarket parts than OEM stuff. I havent seen any uneven wear or anything bad at 8000 on all stock stuff.

It is amazing how "stock" you can keep an LS and have a screaming performer of an engine.
A SBC would need some serious building to have a DEPENDABLE 500HP engine. LS3? Put a cam in it. DONE.
So you have a buddy that can turn his motor to 8+ on a hydraulic roller with non adjustable rockers well good for him.
I don't think you understand how big an accomplishment that is. We're not talking about drag racing a street car, which is barely more strenuous than a fun jaunt on the street. We're talking about road coarse. Engines have to be highly developed to live through that. It's no joke.
That little 346 with 241 heads and stock rockers is a well developed setup and it runs. I've seen the time slips for your fancy "fast isn't cheap" H/C/I 427 and you don't have enough speed to pass that 346. Maybe put down the parts catalogs for a while and try to get your head around that.
It's one of the Morel lifters. They have crap, better, best. Gotta stay away from some of them. I'll see if I can get a part number for you since you asked. There are other brands you could use too. I'll let other people who have more experience talk to that.

That little 346 is of no concern to me and if you think that's all that my car is capable of then your sadly mistaken. It has never dead hooked and all of those passes with the exception of the 11.6 have been on BGF KDW2's.lol.
I could sit here at my home office and go back and forth with you all day every day but frankly it's getting old and I'm on my way to the NHRA Spring Nationals.

What would you say is a good "one notch above an LS7" lifter?

I don't have a wealth of experience so I have to rely on the experience of others. Johnson supported GM racing teams so they naturally have a leg up with knowledge of GM development test standards and some advanced engineering resources. In other words, there's some deep knowledge there. When the LS7 lifter wasn't good enough, GM created the Cadillac Racing lifter. When the Cadillac Racing lifter wasn't good enough, GM worked with Johnson. And the Johnson short-travel lifter exceeded every durability test that the Caddy lifter didn't pass. I would think any of the Johnson lifters are a safe buy for a fun street car. And they have an axle oiling version for setups that generate heavier loads on the lifter. Call 'em up and they'll help you choose. And Manton probably has the most experience making pushrods for use with Johnson lifters. Those two companies work well together and make good stuff.
Personally, I'm not buying Morel, I just know my buddy has had success with it. Morel is trying to play the low-cost and high-end market at the same time and their low cost stuff is junk. I've seen it again and again in my work experience how the low-cost ideas eventually bleeds over into the high-end product and I don't know where Morel draws the line. Johnson only has good stuff and I can buy with confidence.
I used LS7 lifters back in 2011 and it worked fine for some short revs to 7K rpm with the gentle lobes of a Cammotion cam. But I'm too scared to use new GM lifters now. Seems in the last few years I've seen a lot of stories of GM lifter failures (axle failures, rotating in the bore, seizing to the bore). I'm not sure the GM lifters are as good as they used to be. Have you guys been seeing the same thing?

Standard reply you've been giving people for a while. I'm just the latest in a long line.
Your car does what it does and hasn't done anything more until it does. Can you follow that?
Look, the only reason I'm bustin' your chops is because the OP asks for the cheapest, reliable setup and you tell him to buy $1500 rockers. Then you double down on it in post #10 with your reputation. SERIOUSLY?!?! You don't have a reputation that matters. You're a slow *** 122 mph H/C/I 427 LSx. I'm not a rock star either but at least I'm honest about it so people know how to weight the info I provide.
Sorry if I'm blowing up this thread. This kind of thing triggers me, and usually I say nothing.

A lot of people need to say nothing. If you're triggered thats your problem.
Classic LS1Tech. Very little tech, lots of off topic opinions, and a whole lot of call the vendor answers.
it's getting really old. Makes me not want to post here anymore. Everyone's a rock star in their own mind and others are inferior and have a crap setup.
I was going to say nothing but now you go and say that I don't have a reputation that matters? Well what makes you so valid? I also didn't know that you had personal knowledge of my experience and reputation but since we're on the subject I'll have you know that I work in the private sector and have been self employed since 09. I've worked for the man for most of my life but being the man is way better. My reputation has grown a business that's more than one man can handle but good help is hard to find as most people just want to take advantage. It's because of this business that I've been able to invest into my cars and I take pride in saying that the first engine that I built was my LSX427 and I did all the work to my cars so that too is just another one of my accomplishments. I couldn't make six figures building engines though because to do that would require a reputation and probably owning the business. So go on and get the last word in as I know you cannot help yourself and I'll be the bigger man and not respond to anything else that you have to say to me. 28x10.5 slick but spun on this hit too with a horrible 60' but I did reach 125mph so in theory that's a 10 second capable car. Since you've seen my timeslips I'll go ahead and share them here and I'll just assume that you already know I'm good on the tree and that my timeslips have everything to do with a loss of traction.
All of these are with the BFG KDW2's on a Pro Tree with no burnout or high RPM launch! Just me having some fun and not trying to break my 35K investment!
What is the cheapest valve train setup you trust to reliably turn 7500+ rpm. Not at a constant like a circle track car or something, but a street/strip type application.
Assuming the obvious like cam, heads, intake manifold to actually make power at those rpms. Personally I am and will continue to be procharged so that certainly helps with making power at high rpm due to the nature of the centrifugal. Mostly focused upon valve train requirements.
I put over 600 passes on morels link bars and comp cams bsr. 7200 at the shift 7400 at the stripes. And probably 60 or 100 passes at 7800 running heads up stuff. Still going although the lifters are starting to make a little tick. But they have been tough lifters. I use the btr chomoly pushrods.
