Stronger internals

[theangrynortherne]

Hi! I realize this has more then likely been asked but im not sure if the search function on my phone doesn't work or if im doing something wrong but i cannot find anything so i apologize in advance. I would like to make my 190k lq4 last forever and I'd like to get more power out of it. I'd like a new cam, and ive read that while doing the cam i should also do lifters? And rockers? Is that correct? What is the most recommended set of either one?Recommended cam? I'm not trying to be unique if someone has the same setup and its worked for them i will literally do the exact same thing. If its not broke don't fix it if i missed a part to upgrade please let me know! Tyia!

Here is a good thread on what he's getting and how to install it. https://www.tahoeyukonforum.com/threads/cam-swap-question.117036/

One other thing you can do it check the what you did thread and just read signatures. A lot of people will list what they have and it will give you some other info on cam's to choose and what springs, etc... to put in. https://www.tahoeyukonforum.com/threads/what-did-you-do-to-your-nbs-gmt800-tahoe-yukon-today.12502/

Hopefully someone with a cam mod will pop in and give you info on what they have.

This is a stupid question im sure but how do i read sigs? I uave the tapatalk app should i be using s ok something else? I follow red rocket because his denali is the closest i could find to mine but every time i wwnt to look for his posts i have to find his last post to his build thread the search for redrocket does not bring it up. There has to be an easier way to look for people threads. Maybe skip the app and go right for the internet?

That might be because I changed my name to Rocket Man lol. I’m not sure about sigs on Tapacrap but on a browser on a phone you have to turn it on it’s side to portrait mode to see sigs. As far as replacing lifters, if you pull the heads then you might as well do them but you can swap a cam without doing that. Here’s an article on how to do it without pulling the heads. I used 5/16” steel rods but had to grind/ sand one of them to fit in the oil galley holes to hold the lifters up. https://www.ls1howto.com/index.php?article=23

As far as cams, I highly recommend the “Trucker” from Vinci High Performance for its low- end grunt and hp and they have the best customer service. They will get back to emails in hours and answer any questions you have. You will need to do valve springs, hardened pushrods, seals and I recommend a rocker trunion upgrade using Smith Brothers kit. There’s a member here selling the upgraded rockers in the classified section but honestly it’s not hard to do that yourself. I just finished a cam swap in my 08 Silverado and here’s a link to that in my build thread. It details the trunnions and springs better than my Denali build thread. https://www.tahoeyukonforum.com/thr...lverado-build-aka-the-machine.100281/page-224

You’ll need a tune when you’re done too or you won’t get full benefit plus your engine will run rough and might throw codes.
Any other questions just ask.

VHP cam page. They will sell you the kit with pushrods, dual springs, seals. You will also want a good spring compressor tool, I used a single one but there’s dual compressors too. Look at my build thread for tips. I found that when releasing the tension on the springs I needed to use a long prybar to force the springs up as I released the compressor or the keepers would catch and pop off. http://vincihighperformance.com/camshaft spec list page ls truck.html

Oh and there’s links to both my build threads in my sig if you can see it. Otherwise here’s my Denali build, my Silverado I linked above. Beware, my Denali thread is going on 300 pages now lol. https://www.tahoeyukonforum.com/threads/rocket-mans-02-denali-build-thread-aka-the-beast.83457/
