Has anyone bought and run the newer TSP LS7 investment cast, roller tipped rockers? I'm curious how the weight of the roller tip compares to the OEM investment cast rockers. Considering the questionable life span of LS7 valve guides, I'm thinking of buying a set. I just don't want to make that large of an investment if they aren't going to be what I'm looking for. I think the part# is 6670? I like the lifespan of investment cast steel over aluminum, seeing as aluminum can fail after enough cycles, and nobody knows what that number is. I've narrowed my choices down to either TSP, or the latest Yella Terra. Thoughts, anyone? Thanks, guys.......

 

There's a guy on YouTube who put those roller tips on the BTR shaft mounts. Search "ultimate LS shaft rocker system" from ThatEngineGuy. It's a good quality video so you can really see whats up with the parts. I'm honestly shocked no one is selling that as a kit.

 

That's ls3 only. I'm curious if the same strategy would work with Comp's BSR setup.

 

They work fine just make sure you have enough spring to control them. Just by feel between a stock rocker and the TSP roller rockers, the TSP ones are definitely heavier.

I pulled a set off my car and have them listed for sale on CF. If they don't sell, I may throw them back on to take advantage of the extra ~.007" of lift.

 

If anyone can weigh in on this right here,

I have the comp cams max lift ls7 shaft mount rockers. I wonder it’s possible to disassemble the tsp roller rockers and press in new bearings, then install them onto the stripped Max Lift shaft.

I also watched the before mentioned video but BTR advised those shaft Kits don’t work on Trickflow heads

I will say that I have not heard one bad thing about the TSP roller rockers.. FWIW.

 

The TSP rockers ARE available for the LS7, too.

 

Yea I own a set of the ls7 rockers. The TSP shaft rocker system is only available for the ls3 heads. Ls7 heads have the cast in pedestals.

I'm sure these are as good as their LS3 style rocker arms and I wouldn't hesitate to run them.

 

not worth it. 800 dollars of junk lol. why would you spend that much on something that doesnt address or improve any of the geometry issues of the stock rocker?

 

Are they the adjustable ones? If so, interested.

 

don't think so....main reason I never even gave them a thought or look.

 

I believe they do offer them. I was looking on their site after reading this thread yesterday.

 

They are adjustable....lmao with I'd bet it's still the same BS size stud from the factory. 1000 bucks for this BS

Lmao. Add a few Big Faces and get a real shaft mounted system. If someone paid $1k for this
👎

Wait a minute...Are we talking about a hydraulic or solid camshafts and street driven or all out racing applications? Irregardless I think your underestimating the Texas Speed rocker arms but I do agree if it's for racing and a LLSR I'd opt for the shaft mounted system.

 

what is the point of paying for these rockers if they just add weight and dont make improvements in wipe pattern?

 

For one there's no problem with the wipe pattern of a factory rocker arm that is fixed on a pedestal and was designed for camshafts that do not exceed .660 lift. Now if your building an engine that will be spinning high rpms and running a high lift camshaft that exceeds the limits of a factory rocker arm or you're doing a LLSR then you should be looking at adjustable rocker arms anyway and something more stable then a rocker arm held by a single bolt.

Now I have T&D steel adjustables and they're held into place by a 10mm bolt. I haven't had any problems with them. Everytime I've checked the torque on the bolt they've never been loose. It's the locking nut that has loosened on me and those rocker arms are $1300.00 and even heavier than the stock rocker arms.

 

since when do stock ls7 rockers have a good wipe pattern?

 

Are you saying that GM dosen't know how to set up the valvetrain on an LS7?

 

sorta, i mean probably a good 10% of the ls7 cars struggle to keep a valve in the head. last ls7 rocker i seen the wipe pattern was fairly tight but significantly off center. not horrible by any means but usually you spend money on valvetrain to improve it, not to keep it the same or make it worse. im just messing with you tho, but debatably the ls7 in many ways is towards the bottom of list of best gm v8 engines made. not a failure tho, it did what it was designed to do, make big power out of a small block.

back on topic tho, serious question, what can the tsp rockers do that a stock ls7 rocker cant?

 

I bought them and have no complaints thus far. Seem like a good product. Sitting on pac 1209x springs.
