I agree. But remember, Chevy tried the N/A route intially, but couldn't make the emissions number (or so they said). Did they stop work on that engine, or did they continue?? That is the $1M question.

Depending on the stroke I would imagine around 330ci's give or take a few. A guy on tech did a destroked 6.0 turbo build and it screamed to 7500-7700rpm.

There is a difference between retro and heritage. This is about heritage. A car can be totally modern but still follow its heritage.

I didn't think it would be that much of a difference. 6.0L is roughly 365CID. 330 would be around 5.4L. Perhaps a good old-fashioned 5.7L(350CID) displacment engine?

Time will tell, but the good news is, it looks as though there will definately be a Z/28!!

If GM is going to advance(questionable word choice) to OHC, this may be the best avenue in which to try it in a smallblock V8 configuration? I think some ppl would squalk at a SOHC or DOHC in a base SS(weve been pretty damn sucessful with our "old tech pushrods")but to throw one out there in a "special aplication" may be easier accepted and can give GM a chance to show what they can do. Kinda like Ford trying the FPC in the GT350. Could be a "gateway drug" to an evolving application? I cant think of a better application for an OHC project than a car that was known as a high rpm screamer.

[NASTY99Z28]

Dohc? Oh lord I can just hear all the ford swingers screamomng now. They act as if ford created dohc or like its new. Its neither yet they worship it likes its Christ himself.

I am sure that GM will consider OHC. They said they considered it in the C7, but it would add a few inches of height to the engine that would make it too tall. So, if this engine will be used in both the C7 and Gen6, it would probably not be OHC. But if this engine will not be available in the C7, OHC seems much more possible.

It would be nice to see another V-8 of some kind for the Z/28...but I think the more time that goes on the less likely we will be surprised...The LT1 and LT4 I think will be all we'll ever see....

The Z-06 got the LT4....Doubtful they'll come out with another N/A engine that would have been a better choice in hind-sight....I think anything more powerful or unseen will be Turboed or Supercharged....It's the only choices that work for emissions, etc....

I don't think a one-off engine for Camaro only will be made....Everything Camaro is getting has already been used in other models....I doubt we'll see another v-8 that is used only for the Z/28....The circumstances that allowed the LS7 to be used in the current Z/28 will probably never occur again....

[hotlap]

Sounds like he's referring to a COPO type factory race Z/28

it still needs to be a wicked fast track car more capable maybe than the comfort- and driver-oriented models.

Your statement makes perfect logical sense. BUT, Chevy changed the name of the original 5th Gen Z/28 to ZL1 because it uses a forced induction motor (and had other stuff that didn't seem to fit the heritage of the original - like creature comforts). AND, it seems to me as though Mark Reuss is hinting that the 6th Gen will be N/A. AND, the fact that GM was already working on a N/A motor for the Z06. I think it is more likely, that the engine they were working on for the Z06 might be the new Z/28 engine.


Remember the LT4 is the engine that was used in the Z06 and puts out 650HP. The new Z/28 will not have to produce that much power, just enough to beat out the Voodoo, which will have 500+. Perhaps GM backed off the HP of the new N/A motor a bit to meet emissions. It won't be enough and not in time for the Z06, but will be enough for the Z/28. Then you can use the LT4 for a ZL1 Camaro.


Now I fully admit, I am using a huge amount of speculation here, and perhaps it is just wishful thinking on my part. You might just be right.

[Z/284ever]

The Z/28 is already in the pipeline and will be here sooner than some people think. The only question is, will it remain true to it's roots and have a badass, free revving, normally aspirated smallblock.......or....will GM screw the pooch and put a version of the LT4 in it, a la C7 Z06?

GM, you know what we all want. Do the right thing!!!!

Who is "We"? The people who aren't buying the current "True to it's roots" Z/28?

Do you think they would buy it if it was $50K instead of $75K? Ford seems to think so.
