L33 questions

I got a l33 out of a 09 sierra I'm planning on in my turbo fox. I plan on using a ls6 cam with my tc78. I know it's a 3 bolt and the original was a 1 bolt. I have the new cam gear along with the lingenfelter.box and ls2 or 3 Valley cover ( can't remember which one). Also have ls7 lifters and trays. Question is what front cover and timing chain do I use? I read about the ls2 chain and tensioner?

I know this has been covered somewhere but can't find a definitive answer. Thanks

I found some info on lt1swap where he was talking about the afm delete which this motor had. It's being deleted as of now but he didn't mention anything about the front cover. I'm assuming he uses the stock front cover accessories. Anybody?

The last year for the L33 was 07.
Why not use the stock chain?

Unless the engine has VVT, then you should already have the cover you need.

If it's an 09 engine and came out of a Sierra and has an aluminum block then it is a LH6...

This is a Gen IV engine and better than a L33...except for the AFM and VVT...

Im pretty sure it was an 09. I didnt see any VVT stuff on it though. The front cover has a sensor and bracket on it that is curved around the boss and is about 4 inches long. I could reuse the stock chain. I think its just cheap insurance to change it. Even though you still have a chance of it breaking even with new chains. Thanks for the replies.

You're right, no VVT on the LH6...Here is a Word document with all details...

Just ditch the AFM and you'll have a good base for your build.

Just found out that the truck year is an 07 not an 09 like I originally thought. Either way i know it had the AFM and I dont think it had the VVT. So do I just use the original front cover correct?
