Looks like we are back at it....another forum misguided attempt to steer the world away from Yella Terra products again (and for all the wrong reasons).

For the record I plan to post a very in depth post about Yella Terra in the following week to clarify a bunch of things and give the people willing to read and consider a very fresh and enlightening perspective.

After all, few here could be qualified as much as I to discuss this because no one that has posted in this thread has the data and the feedback I do both installing and recommending this product for well over a decade. When you have hundreds......yes literally hundreds of combinations out in the field with your name on it that run these rockers arms that sort of makes you an expert by default on this particular topic. No one posting here is in the position I am to know just how good (or how bad) this product is....and if the feedback wasn't good and they weren't performing for me I assure you I would not be recommending or using them a decade plus later.

Let me sum it up for you. I run Yella Terra Ultralite rockers on 98% of my cathedral engines....95% of my LS3 builds.....and 95% of my LS7 builds. Good chance if you have read about a successful build utilizing Mamo products (be it now or a decade plus ago) it also had a set of Yella Terra rockers included in the build. In fact barring just a few all out race builds, I have run Yella Terra products on pretty much every LS build I have been involved in for close to fifteen years now (Google and you will see how accurate that statement truly is).

To wrap things up the YT Ultralite is a purpose built rocker that I have had incredible success with for well over a decade. They had some teething problems with the original Gen 1 cathedral design 14 years ago and got a bit of a bad rap due to that in spite of updating quickly to a much more reliable Gen 2 design and ultimately an extremely reliable Gen 3 design back in 2011 - 2012. The cathedrals being offered today are still the Gen 3 design and their reliability record has been excellent. Note the newer products more applicable to this thread (my LS7 and LS3 gear) are an even newer 4th gen design and they have been rock solid for me. Results speak volumes here once again. How many Mamo LS7 combos have you seen now rocking dyno after dyno....small cams...medium sized cams....big cams....doesn't matter....every one of them running Yella Terra rockers and the other Mamo cast of characters. Bottom line....they work extremely well....they are cost effective and you guys should be glad you even have this option available if it fits the type of build you are after (which quite frankly is 95% of the guys reading this). Again....more on this in my own thread I will be posting on the topic soon

FWIW I'm away on a brief vacation to the east coast visiting family and just invested three plus hours typing and dealing with this because I felt the need to set the record straight and its a topic I am very passionate (and knowledgeable) about. Theories and valvetrain buzzwords are bullshit when you have hard data and results to compare against them and I'm chock full of hard data and literally 100's of proven combinations going back over a decade....I know what parts work and what parts don't work and I surround myself with proven parts that work. With the proper set-up the YT rocker arm is an extremely capable rocker arm for a very good price....but the price is just a perk. The reason I run them personally and for most of my clients builds is that its a purpose built part the fits the parameters and requirements of my builds perfectly.

I will get into more detail why that's true in the thread I have been discussing when I come up for air after returning to Los Angeles
