Shaft rockers are the bomb! I had T&D rockers in my blown endurance boat and they were bullet proof. Can’t emphasize the importance of deflection from any source to valve timing. Not only in reliability, but also power since this consistency helps promote even power among the cylinders from revolution to revolution.

[@Wilson-kd2sl]

100% T&D make great parts! I'm running a set on my 6.0 with L92 heads. I picked up .050 on my ET in my bracket car. Made the switch to shaft rockers for more stable valvetrain and with that came a better performance

[@stevemorgan3512]

[@tom-mo2pd]

Hi Which ls e give do you have ? I have also been oozing at the Brian tooley shaft upgrade but I don't know which rockers and springs will be compatible. I have a texas speed bald eagle cam in it already so wasn't sure which is going to work. Can you help ?

[@arturozarate1752]

Installed and work great. Please read the instructions thoroughly and read again before installing! Can't stress that enough. Especially when installing on the engine. The pair will be tightened down together. I used ARP rocker studs and that made it even more fun. Oh, stop using 5/16 dia pushrods. BRIAN TOOLEY RACING sells 11/32 pushrods in 0.080 wall. Same price if not less than a 5/16 and noticeably stronger. Since we're all in for the "RIGID"

[@jasonelliott5196]

Have you pulled them off and checked the bottom side of the fulcrum/shaft. Mine showed west after only 1000 miles

[@walasiewicz]

Holy shit that's a huge cam your running in that thing. Dude you are engine smart for your age and have a great understanding for physics and the way it all works. I'm impressed and i don't impress easy. I'm 53 and been building engines since i was 16 and i don't like many people cuz I'm a quirky mechanic but i could hang out with you

[@mythos000000025]

I used bar's shaft system in my build and I thought about the magnum xl rockers...glad someone tried it..I do wish btr would sell this as a whole kit

[@LoneWolfSnowplowing]

The shaft rock kit is pretty slick. I just installed the V2 version on a 2005 Corvette. I bought it with new BTR rockers already installed. Engine has a 7,200 rpm limiter and makes about 850hp with a Magnuson supercharger.

Part number on the yellaterras you ran? Looking for some for my 416 can’t decided which yt’s i want

[@petercheesman2449]

Great idea and video. I seek to do that too. Was the roller contact central over the valve? My understanding is that ideally a lap rocker arc sweeps towards the pivot, but a roller rocker can be set to slightly sweep away, then bac towards the pivot, keeping contact over the centre of the valve.

[@hambone7777777]

Good, stuff. Shaft mounting for the BBC is on target. How about that 632cid, mate?

At this higher level wouldn't you be better off with bushings instead of needle bearing?. Love your tech.. thx man

[@tonkatoytruck]

My machinist sees far more bushing failures than needle bearing failures.

[@BlueOvalZ1]

Question: As I was duplicating your set-up (using BTR's changed design of thrust washers rather than circlips now...ugh), I wonder if you've observed any issues related to the different expansion coefficients between the steel parts running the length of an otherwise all-aluminum head, when everything is up to operating temperature?

[@jamesburgess8675]

I have a daily driven cammed 6.2L ( L86 ) making 417rwhp im looking to take this build to the next level can I consult you on what parts I would need to make the motor bullet proof? Planning on running a 2.9L Whipple to hit my 500rwhp goal Thanks!

[@EliteAmerican1776]

I was wondering I have a 2014 LS4 430hp what’s your recommendation for Roller rockers and rack to sit the rollers to get the strength im not racing or doing those things I’ve only got 33k on the motor

[@BurbanOverland]

you talk about the valve tips getting messed up under spring load of 420 lbs and more. my springs are tested at 415 lbs at .660 but all my exhaust valve tips and 1 intake valve tip are mushroomed. should i upgrade to the roller rockers?

Also which cam would u recommend

I know this video is a year old but I’ve watched this video many, many times before posting this. I was looking to do the same thing but I got to thinking, can I do the same thing but with 1.8 rockers? I know that the push rod length will change as well as the cam specs. I’m also sure this may also cause piston and valve issues. What do you think?

[@jakeparish1991]

Would those rocker arms work on the comp shaft rocker system?

[@HybraTater]

Will the TSP 1:8 steel roller tip rockers work with the Comp Cams BSR shaft rocker system for the GM LS7? I obviously love all the benefits of the roller rocker, and the strength and durability of steel rockers especially on the LS7 valve train geometry. I will no longer run aluminum rockers even on a relatively mild 228/244, 630/621 118+3 street build (no matter who makes them) because of the high failure rate of aluminum rockers. I run with open spring pressures of 436 with PAC 1207. BTW, YT Ultralights are beautifully made, but will not hold up for open spring pressures over 220lbs, as stated by YT. Who the Hell runs 220 lbs on any cam upgrade? Rediculous .

[@williamkittle9858]

I have a 5.3 LS with practically no oil pressure on. I put a new oil pump and it did nothing for it you got any ideas ???

[@sic7camaro]

[@DesTakeFlight]

How much to have a set like this done ?

[@butera76]

I'm wanting to go this route. In 2019 replaced the rockers on my Pontiac G8. I was going to leave the trunnion upgrade to my factory but wind up buying some prw for roller rockers. These rockers were definitely heavier than my factory but I figured with the roller tip to reduce friction and the sturdier body would give it less deflection. I figured maybe a couple horsepower for the roller tip reduce friction, an stability. Long story short the needle bearings wound up failing on the roller fulcrum on several of them! Can I use these on the shafts with a new bearings and shaft mount supplied? also these being heavier would I benefit on going with the factory body style like you had with the full roller tip? or Would these be fine on the shafts with new bearings?

[@jasonelliott5196]

Then Btr shaft kit comes with bearings that fit stock rockers and apparently these Texas speed rockers

I've always wanted to put together a high rpm engine. No matter the final power output just the idea of 8500rpm+ has always been something I I dreamed of putting together . So here's my question. I don't know much about the 4.8 ls. , but Is it be possible to put together a long rod 4.8 and would it do what I'm asking with the right internals and valvetrain. And if so I wonder what kind of numbers it would make

[@wed3k]

Probably need a custom piston

[@leejordan2750]

why not destroke a 6.0? just use a 4.8 crank. can be built with junkyard parts, you end up with a big bore/short stroke that you can then use almost any gen3 or 4 head to feed because of the 4.00" bore. then pick how hard you wanna turn it and put the top end together accordingly.

[@walasiewicz]

Anything over 6500 makes me cringe and cover my noggen. Over 7000 you're only testing your rotating assy and hanging on for dear life. Why worry about that extra 1000 rpm there's nothing happening way up there accept the risk of destroying everything. Well built and components matched engines can make all the power you need down low and never have to put it up in that high risk zone. If you like listening to metal in a blender build yourself an 8G motor. Hope you have a lot of money

[@mikehoncho5389]

@@walasiewicz pro stock and nascar engine guys probably won’t agree with you on that. It’s easy to build a engine to make power above 7k rpm’s especially a LS.

What do you recommend for rebuilding a original stock LS1 from a 2002 Camaro SS ? I want to upgrade it and add a little extra power but nothing crazy and can use 91 octane. It’s still running well but has well over 200,000 miles on it

[@arturozarate1752]

Bump the compression up to a solid 11:1. Have solid head work done, ie. CC'd, real valve job, upgrade the valve train(cheap Chinese new is not an upgrade), tie bar lifters, Cam Motion LLR, 11/32 pushrods(3/8 are hard to fit), stock crank, Gen IV rod with new ARP bolts, the lightest piston you can find with the top ring 0.125 down from the crown, low tension rings(maybe ditch the engine 2nd😉), quench 0.038 to 0.048(NO MORE NO LESS). It'll drink 91 to 93 all day. That should get you in the ballpark of being where you really wanna be! Just my educated 2 cents. Sorry if you felt overlooked. People get busy. Hope this helps.

[@arturozarate1752]

Oops.....you said "a little". In that case get a tune up. TR6(8), MSD wire set, Ford Motorcraft PM-2(2 cans). Spray the PM-2, generously, into each cylinder through the sparkplug hole. Use a long flexible straw from a can of Seafoam(throw the ENTIRE can of that shit away). Let soak overnight. Place towels near each sparkplug hole to catch anything that comes next. Spin the engine over to expell any PM-2 still in the cylinders. Install your new parts, change the oil and let the smoke show begin. Video and post somewhere. Let the engine come up to temp by cycling engine speeds from idle to 2k periodically. Test drive and blow anything left out. That's the recipe for the best "Major Tune-up". I'll take the Pepsi challenge any day with that. Essentially what you're doing, actually the PM-2 is doing, is releasing Millions(and MILLIONS) of hydrocarbons built up over 200k from the piston ring lands, compression rings, and most importantly oil control rings. Seriously, do this for a little more power. Either way you just got the best recipe you never had.
