VVT is nice, I wonder how restricted those motors are. A tune should bring it alive for sure!
GM should have really offered these with the 6L90e for better fuel economy
So was it the 6L80e that CPWire used then; I do not recall them having to modify the tunnel for their install. I know they had to do some work with the cross member, but that was to be expected.

Time to go dig that info up!
I went back and read all 10 pages, the 6L80e fit fine!

It was the 4L80e that was said to be to big for the tunnel; even though CP Wire make it work with no mention of tunnel mods.
Its all good in the hood!

Team effort here :high5:
Vvt on a single cam motor is some neat shit.

There is one of the cam companies making special cam phaser so you can pretty much run any cam. That all came about from the motors that have the displacement on demand

Well guys not to insult anyones intelligence, but LS1Tech is the place to go for anything LSX based. Here is some reading material for y'all!

5.3L please help! - LS1TECH
I got that.

That was a 2 second search on there. If you go over there and do some research you should find the info you need.......I can't do it all for you.

All the info I needed for my swap and knowledge was attained there.

Thanks chief! I've been on LS1tech since 2006. Not a ton of Colorado specific info there. I thought that 355 info was the purpose of this forum.

I know I'm new here, but I am not new to LS engines.

No offense, but:

Well, gee wizz... thanks so much for performing a 2 second search and then providing me info irrelevant to my question...

When I asked the question, the intent was for someone (obviously not you) to answer if they knew the answer already.

There seems to be a large amount of Colorado/Canyon specific information here that is largely ignored on other forums.

You see, when you start any comment with words like: "not to insult anyones intelligence" or "no offense, but" you end up doing exactly that. You know you are about to be insulting, that is why you say it to begin with.

I realize you are a mod, and want to stay active here, but if you don't have anything valuable to add, maybe just don't post on tech specific questions you do not know the answer to.

I have read other similar comments on here by you. A good example is in the LS7 6L80E Colorado build:

I can only assume you have built and tuned several supercharged LS7s in your day.

Maybe rather than posting 28,000 times just parroting info you read on the internets, you could focus on providing useful info on things you have first hand knowledge about. I searched your threads to make sure I wasn't going off half cocked here. You have contributed some good stuff.

So don't worry


Sorry to waste a post of my own, and sidetrack a good thread.
Yeah the staff here made me a Moderator and member of the MTS crew just because I'm a nice guy! :handy:

So since you have been on LS1Tech for 6 years you know everything and here for 2 minutes you think you can start a pissing contest...ok, well have fun with your swap.
