GM's 2007 60V6 Lineup

[RacerX11]

the L66 3.5l sohc motor is a honda motor

And has been repeated several times already in this thread.

Wholy shit, The camaro is getting a 3.9 when it comes out.. and hopfully a 6 speed... U know how awsome that is for the rwd crew!!! and that will be alot easier to find in auto wreckers than some caddy... Im already tryin to plan what to put it in... Prolly build an aluminum frame and put a swanky fiberglass body on it

[SappySE107]

Where did you see that?

right there.. i guess this one says 3.6, but on a camaro forum i found 3.9, ill have to find that forum again..

My money's on the 3900 going into the Camaro. The price point of the base Camaro won't be high enough to allow for use of the high-feature 3.6 without losing a lot of profit margin. The 3900 probably also has a tiny bit more low-end torque to help move the (I'm guessing) 3300lb. + Camaro during normal driving.

I wouldn't look for the high-feature engines to be part of any cars manufactured by GM under the Chevrolet name.

Edit: That's just my opinion, though. There's always the possibility that GM will continue to screw up their stuff. Or they could just have a different line of reasoning. :P

GM has made some squirelly mistakes the last few years, especially with the Pontiac lineup.
i.e. #1 - discontinue the grand-daddy of sport muscle cars - the Firebird. This requires no explanation as to how stupid of a decision this was.

i.e. #2 - build numerous SC/T Grand Am concepts, a total of 15 prototype blowers for the 3400v6 SC/T's; then relase an SC/T body kit on the '04+ GA's (which about doubled sales of the GA's overnight), then discontinue the car once it becomes GM's best selling vehicle - they should've gone full production of the blown 3400v6 SC/T Grand Am's, and dumped the Vibe, the SC/T's woulda sold like hot cakes.

i.e. #3 - finally put a v8 back into the Bonneville after 20 years of weak 6's, make it more powerful and sportier than the Cadi's, then discontinue it - WTF?

i.e. #4 - finally build an AWD off-road capable Aztek (which was one of the safest and most capable SUV's on the road), and discontinue it while replacing it with the truly ugly, non Pontiac inspired design of the Torrent, take the dart off the front and slap a bowtie on it - it's an Equinox.

i.e. #5 - discontinue the 2.4LQ4, even though GM performance finally released a roots style supercharger for the Q4 which coulda gone into the production Sunfire's, Cavalier's, SE2 Grand Am's (this woulda been great for the GA, along with the blown 3400v6 being offered - your choice, blown Q4 or blown v6!), Alero's and every other FWD vehicle stouting the Q4 motor, coupled with the fact that the Q4 when properly maintained is a friggin rice killer from hell - y'all see my point

i.e. #6 - announce that the GTO will be discontinued yet again (although rumor says it'll be back in 2010 on the zeta platform), because the 2-seater Solstice is more cost effective to build (BS, IMO) - although sales of the Solstice have been lagging, I think too many people remember the antics of the last 2-seater that Pontiac offered.

there's more, but this get's old. I really wish the bean-counters at GM could look at actual vehicle trends, instead of just numbers

[sharkey]

1)they killed the f-body cause it wasnt selling, hadnt been for years.
2) a 3400s/c would have cut into the grand prix to much, why have 2 completly different supercharged v6 motors???
3)bonneville- gm had to cut cars, why sell 2 cars on the same platform under the same name???
4)aztec was ugly and was far from a cabable offroad "suv" (more like overglorafied mini van)
5)the 2.2 eco motor is a way better motor overall. its much more up to date and is more versitile. the design allowed more variance in displacment, vvt capability, big power turbo motors, stump pulling supercharged motors, and all on a global level. gm brought out the blower when they knew the eco was replacing the tc, so why build a blown tc cavy when in a year you are gonna throw it out the window, and a few years later kill the car off.

6) the gto, well, cant form an opinion of them cause gm cant sell em in canada, they doint meet the safety standards and gm wont conform.

LOL!! That's how Pontiac advertised them, too!
Can't argue with any of those statements, either. But, the ecotec still hasn't won me over yet. I like how you'll get one now and then that leaks oil right out the side of the block.

[sharkey]

havent yet seen or heard of one of those, but i would guess at some point they must have had some porious castings for that to happen.

im liking the ecotec for a 4 cyl engine. in the few years its been in north america, they have done so much with it, and more is to come. a 2.0l turbo that can make 260/260 is dam inpressive. time will realy tell how this motor is, but i havent heard of any inherent major problems or flaws in them so far. other cool thing is the fact that gm wrote the book on how to produce 1000hp from the eco.

[prophiseer]

1k hp?! I didn't realize they were squeezing that out of 'em already (I shoulda figured, though, a few GM performance teams got those numbers outta the Q4's).

I've seen quite a few in the shop, the block oil leaks only seem to be the 1 coupla years the motors were in production - prob due to the porous castings (they look like styrofoam).

From what I can tell, it looks like a lot of the technology and research that went into the Q4's was applied in the design of the ecotec, but at least that's the way it looks.

[RacerX11]

More like GM learned from their mistakes, and all the things done wrong with the Quad4's were done right with the Ecotec

[sharkey]

gm built the ecotec as a new motor, clean sheet of paper. of coarse they learned a lot from the quad 4/twin cam, and using what they learned, they discovered what to/not to do in the eco.

yea, they are pushing 1000hp from the ecotec. actualy, they are pushing over 1200hp in the drag cars, but the gm ecotec powerbook only tells you how to make up to 1000hp. the ecotec drag cars actualy hold the pro fwd records, and were a threat in pro rwd, a class usualy dominated by 6cyl cars. gm makes a performance head, block, crank, and a lot of other parts to make these numbers.

1) Are these engines basically the same engine, block wise, as available in say, a 83 camaro or s-10? Or 88 cavalier? Or 91 lumina etc.?

a) please describe, in great detail, the differences between all engines. I.e., LZ4, LZE etc.

2) i know the 2.8 is 173 CID. Why did they "go back" to 2.8 displacement? Because of turbo?

a) Please list exact cubic inch displacements for all of the current engines.

Almost everything you are looking for is located at the above link.

None of us are affiliated with GM, so getting the detailed information and reasons GM did what they did is pretty difficult.

Some things have remained the same on the blocks, others have changed. Especially, mounting bosses on the sides of the engines.

You will find some of the new engine specs here.
