SDPC Tech Tips: Trunnion Upgrade 

The point about the CHE bushing weight not being factored into the valvetrain weight is golden

laughed out loud when the 3rd arm came up with the trunnion in hand

Did you see him push that valve open? What a monster! I couldn't even budge mine.

really well put solid answers thank you

Just got my set of Gen Iv CHE kit and mann they feel like quality . A motor you should never cheap out on !

I'm doing a cam kit in a few weeks 223/228 @.058/.0588 @114 and dual springs and dod delete , I've ordered the comp cam press in bush setup for piece of mind for my daily. It makes sense to do everything while the heads are off. Only a few hundred dollars for peace of mind.

Thanks just ordered some from you

Thank you very much.... CHE it is....

thanks for the info

Great vid

Love the vids I really appreciate the knowledge! So I went with che with my build in my 05 ls2 gto with a medium 232 234 600 600 cam good springs Delphi ls7 lifters and more . I'm a street guy who daily's my car with some spirited pulls here and races here and there. What's the longevity until I need to replace my che bushings? And springs at that?

I close my eyes and hear Chris Pratt… anyone else? Great vid too 👍

Great Tech! Any plans to do a 5.3 cam test on the L83 like you did with the LM7?

Great video nice to know this because I got a few needle bearings on my oil plug magnet 😔 I have a stock 2000 5.7 ls1 trans am. Do these upgrades fit my stock rocker arms?

Even if you have a stock ls3 or lsa.. DO THE CHE BUSHINGS. Why? Over kill for longevity. Not only that. But let’s be honest? We rev the hell out of these engines. We spend time in the higher rpm’s because that’s what we love. This should be a must and recommendation by default. I hope someone understands what I’m getting at. It’s worth the money.

Great video, so I have a 2012 GS with ECS supercharger, 8lb boost. Makes 592hp to wheels. I rest of the engine is stock. Do you recommend this upgrade and also what about lifters? Not sure if with stock cam I’m going to have issues.

How much RPM can the comp trunions take? Rev limit on my L76 is 7000 rpm

Does the trunion start ticking when it starts wearing?

Is there anything unique about the retainer clips used at the ends. Previous owner of my car (08 vette, ls3), did the upgrade set with the bronze bushings. I pulled the valve covers off and found two of the rockers to be off center and have broken retaining clips on one side. Clip was still on just pushed to the siding and missing one of the snap ring ends for the pliers to grab at. I want to make sure I can repress them straight and add a new retaining/snap ring from hardware store

So my valve springs get stiffer?

Hey sir I have a question. When you remove the rocker and do the install does it need to go back on the same valve or does that really matter? 130k mi motor. Has a bit of surface wear where the valve runs but not to bad. Thank you in advance.

Anyone know if the bushing trunnions will reduce typewriter ls click?

I got one question I just got my first LS it’s a VE SSV Holden Commodore aka G8 Pontiac with the L76 now I know nothing about wanting to work on my motor for someone like me we’re do I start also I do have A DOD delete Cam kit Custom 2 1/2 inch exhaust extractors and a intake but want to do Internals but don’t know anything about besides names of things from trying to learn myself

Hi I just upgraded my cam shaft in 06 GTO wondering if I should upgrade my rockers too!?

What lift and rpm are the stock trunnion able to withstand?

How many miles can you get from the CHE bushings

Dude has 3 hands 😂

CHE vs Steve Morris durability?

ah

Comp cam are junk CHE are the best you can buy

Nothing but trouble with these trunion kits, they are all garbage especially for the street. Do it right, get some Yella Terra's and be done.
