LME heads purchased in 2018 and I'm still on a hydraulic roller with the T&D pedestal mounts but the 01 cam is 243/251, @.050 .661/.633 115+5 on 1.8's.

 

I just weighed one of my yella terra adjustable rocker arms, Damn your T&Ds are 75odd gram heavier.... Thats a LOT....
No sign of valve float?

 

Haven't noticed any signs but then again I'm not spinning to 6-7k all the time either. I've been told that overall weight has nothing to do with it but more of what the weight is over the valve but that time to replace springs is here and I'm wondering if I should go with a stiffer set.

 

Stock rockers with Straub bushings.


Harland Sharpe's


T&D Stainless Steel ones. The motor does seems to respond better with the stock rockers with the slightly longer 3/8 purhrod though.

 

What’s that white powder on the scale?










lol

 

My TD rockers are 173g and 161g.

 

IDK....Maybe we should get it tested. Not sure there's enough there for me to make a positive identification but I can see the implications mounting. BTW what do you do for a living Jim? Are you buy chance a peace officer because that's the feeling I'm getting here.

The high cost of living is nothing like the cost of living high. JJ

 

I did have a set and like those they were for the LS7 factory heads. These one's are for the Brodix BR7's

 

Makes sense! Yeah these are for factory LS7 (except you need to grind on all the pedestals to make them fit...)

 

And are scales are also in agreement!

 

this is a yt exhaust, add a few grams due to damage from when spring broke


this is over the nose, scale bounces around by 5g goes as high as 19g

 

Looking at the pics there not apples to apples , all have shafts where the yt only has trunnions

 

If I had to guess I’d say to be somewhere close you’d add 50g for shaft to yt weight . The yt shaft for intake n exhaust weighs 150g
Be good to know the t&d trunnion weight
If that’s the case the T&d and yt would be very close to same weight...

 

Overall weight means nothing from a performance perspective. It’s the nose weight that you have to look at when comparing rocker mass that the spring will see. Here’s a couple pics…YT adjustable vs. Oem LS7 rocker nose weight comparisons. I left the needle bearings in the YT’s so that added a few grams, for the record…

 

To Real People .......

If We've got this Much Money 💰 Invested

In the Hell are We talking BS rockers?


Jesel or Crower ...T&D shaft mounted....

What Rocker arms Win Championship's?


Common sense with $
Steel Doesn't Move and what ever Extra weight used with the Rocker Doesn't Equate to weight nor Mass ..with the System ....

Stocker rocker wins again!

 

[QUOTE=01CamaroSSTx;20364190]Hard to beat, no doubt. Lightweight and strong.

 

Lil ***** Small cam and it's lift .....


Stiffness ....Lose Weight in Valves, springs Retainers, etc....




It's Called Deflection.... WORDS NOT USED HERE AND WHAT HELPS.

 

Only thing to Help a Stud mount is a Girdle....


But Tony Mamo did this in a Test.


Stud vs Shaft mounted with the 383.... Don't believe he or they had a Girdle @ the time.

Still Don't ....
