Ls1 cam upgrade

I have a maf, I think its faulty or dirty.

I did a compression test and that came out 140-149 on the cylinders. I checked the maf and found the plug had come out. Looks like I need a new maf

That’s great you found a relatively simple problem to fix, way better than if you were down on one cylinder!!

I would have been shattered if I was down a cylinder. That is probably by I had a shit dyno as well. Haha

Are you running the maf with the new cam?

[ChrisMParticipant Melbourne VicVN Calais LS1 View build HERE Member since: August 16, 2017 Posts: 140]

I’m not planning to. I’m just going to get one off a mate until tuning time.

Took it for a drive and no power loss now.

So i have finally got around to installing the cam. I still have a little bit to go.

Nice work, messy job isn’t it.  I guess it gives you the chance to clean it up a little whilst you can get at it?

its actually not too bad apart from the alternator bracket. Going to be fun getting the old graphite head gaskets off. I think im going to use the gasket remover spray. I have the lifters soaking in oil. I have done the valve springs in one head, i will do the other tonight. I still have to drop the sump to do the oil pump then i can do the timing chain.

Does any know if it is worth doing the trunnion kit?

I was highly recommended to do it.  If one let’s go, and the needles go into the sump you are in for a world of pain….

Thank you Gary. I just ordered the Smith bros set

Nice, they were actually pretty straightforward to fit, just be methodical!

Having access to an arbor press helps a lot too.

I recently installed a trunnion kit.
Use an arbor press or a bench vice, it’s pretty straight forward once you get a rhythm going.

It definitely makes the valvetrain much quieter in my experience.

[ChrisMParticipant Melbourne VicVN Calais LS1 View build HERE Member since: August 16, 2017 Posts: 140]

I saw a video of using the vice to press them in.

My Trunnion kit was delivered today so now i can start to finish off the heads.

Do me a favor bro, put some tape over those inlet ports!!  I shudder every time I see a pic of them open like that, one washer or whatever accidentally falls in there that you don’t notice and “boom” on startup

[ChrisMParticipant Melbourne VicVN Calais LS1 View build HERE Member since: August 16, 2017 Posts: 140]

Yeah i know, There is tape on them just not in the photo. I was going to put the manifold back on. I ran out of time so i put new tape on.
