With the Beauty cover off? That aint no Northstar! Looks like a good ole LT1 with a 32V head on it. This is not the same motor in DeVille and Seville. Who Ya trying to fool Dave? Not Me :nono

How long do tou think it will be before Corvette tuners start dropping "real" Vette Motors in the XLR? Not long before we see someone make a Z06 XLR!:thumbs :yesnod

It's definitly not the same as in the De/Seville but it's not an LT-1 either. And even if thats what they started out with, once they change it from pushrods to 32 valves, there isn't much left anyway:cheers

It's the next Northstar

The attentive XLR student will remember that 80% of the parts are new in the development of the longitudinally-mounted Northstar. That would account for the different look.

Occam's Razor.

Well maybe new to Cadillac but not to Chevrolet:smash
You need to put the mallet down. All those blows to the head can't be good for you.

What Chevrolet has ever had a Cadillac engine?

Dude, they're new parts. They haven't been in ANY production car before. It's a new version of the Northstar. En oh are tee eich ess tee aye are. It is not now nor was it ever a Chevrolet smallblock.

Do you read any car magazines? Have you read any of the articles on the XLR? Or do you think they're all part of the big deception?

BTW, the U.S. really did put a man on the moon.

If you look at that motor without the cover on it looks more like an LS1 then any northstar I have ever seen. It might be 80% new the same 80% new the C6 engine will be. You must not remember the late 1970s and 80s when GM engines were interchangeable Buicks had Chevy Motors Pontiacs had Olds engines etc. I would not put it past GM again. Get a look at this motor with that plastic cover off of it and you will see what I mean. Just what kind of motor do you think is in the Escalade??

"If you look at that motor without the cover on it looks more like an LS1 then any northstar I have ever seen." Because it's longitudinally mounted, it has aluminum heads, a plastic intake, and wiring draped over the heads. You need to get out more.

"It might be 80% new the same 80% new the C6 engine will be." No it is not. It's the same 80% new that the SRX engine will be, because they'll share an engine. XLR and C6 will not share an engine. It's just that simple. It's a fact. It's been published. There are a lot of sources of information. You might try reading something some time.

"You must not remember the late 1970s and 80s when GM engines were interchangeable." I remember it quite well. It doesn't change the fact that what's sitting in the XLR engine bay is the next-generation Northstar engine exclusive to Cadillac. Did I mention that you need to get out more?

"Just what kind of motor do you think is in the Escalade?" Oh, you mean the truck? A truck motor -- the intake and programming of which is exclusive to Cadillac, by the way.

You know, your lack of awareness of well-known information is amusing. I withdraw my recommendation that you get out more.

I have seen the C6 engine installed in a C5 for testing. Trust me sweetie its the same motor but for the 32V heads. Dont forget the CTX is getting a version of the Z06 motor next year. Then it will switch to the new C6 engine shared with the XLR but will not have the 32v configuration.

Trust you? You've seen the C6 engine? You wouldn't know the C6 engine if it fell from the sky and landed on your head. Though that would certainly explain some of the completely ignorant and delusional posts you've made.

The Northstar engine is four and a half liters; LS2 is six liters. Northstar is DOHC; LS2 is cam-in-block pushrod. They're not the same. Run your post count up as high as you like, it won't make them the same.

Next you'll be telling me to look in the Mustang Cobra engine bay for a peek at the next Buick powerplant.

You got nothin'. Except maybe imaginary friends who work at Generic Motives.

My cat knows more about XLR than you do. And he's a dumb cat.

Enjoy your Chevrolet Northstar powered Cadillac Corvette. I'll tell the attendants not to buckle your straightjacket too tight.

All I can say is you will see in due time. Don't be fooled by displacement or piston bore size.:yesnod

Well I guess all the training materials and all the instructors GM has are telling us all the wrong info.? Seems kinda foolish to me.
I have seen the engine, in and out of the vehicle and it does not look like an LS1 or maybe that is a Northstar I have on the floor at work:(
