Top of my want list

This is at the top of my want list. Would it be possible to replace my doggy 4.2L I-6 with this?

Anything is possible, it all depends on how much money you want to spend or if you have the skills how much time you want to spend.

I've already seen an LS1 installed into a Colorado, which has a shorter engine compartment than the Envoys/Trailblazers, so it should be possible dimension wise.

OR you just have to wait until next year when the Trailblazer SS comes out which has one of those perdy little things already installed. (at least thats the info I've read)

It's not the same perdy little thing as he pictures above though. That one in the Envoy or TB makes the SS seem a bit weak

BTW, the Envoy Denali currently has the 5.3 in it now, doesn't it?

Do you recall the name of the installer and perhaps a contact phone number?

The Denali Envoy was supposed to start production last week of January '05. They will have a 5.3L V8 as standard. I plan to go to our local spring auto show next week. They probably will have one on display there.

Hey, I PM'd you with a name and number of one installer working on a Colorado right now. I also got this link from one of the guys on the Coloradofans forums. This is the original guy to put an LS1 into his Colorado.

Perhaps you can contact him through this site and get what info you need.

Hope that helps you out.

Ozrein:

Thanks for the PM and link above.

I'll do some contacting. Looks like the PCM is gonna be a bish to get worked out. I'm thinking swaping the engine would be the easy part, getting it to operate properly without any throwing of codes, etc. will be a real challenge.
