To get a 3850 lb. Gen-5 to equal BOSS stats (8.18 lb/hp) requires 471 hp. And more horses if the car weighs more. Just to EQUAL the BOSS, not to beat it. There's no RPO-ready LS3 makin' 475+ hp...but there IS a 500 hp. LS7...ready-willing-able...

I do NOT see CAI, gears and tires and a Warranty tune making up the acceleration gap between a mid-12s BOSS and a 13-flat LS3...but I DO see an LS7 covering this, easily...

Remember, a Warranty tune will leave some ultimate power in the ECU...just like the LS7 does...
Lowdown, this wouldn't be a Z/28 or a fair fight with a BOSS. Strictly an HO type SS that would bury a GT alive. Something for the current SS owners to trade up to without a lot of money. A hold over until the Z/28 comes out in the Gen6.

Cam I understand your point...SS+...but there are those (a legion of 'em, actually) who think an "LS3+" will be enough for a Z/28...

I'm stating that an "SS+" should not be considered a BOSS-basher. But I fear anything produced 'tween the SS and ZL1 will, by the media and others, be considered a BOSS-competitor, period.

"IF" there's "room" and "time" for one more Camaro version, this-Gen, why bother with a less-than-BOSS-bashing version? Just build what's needed...

Anyway, so you are thinking of something beyond the mainstream performance V8. But, from your earlier post you don't seem to think that it should be the one that will be replacing the LS7. So, something in the middle then. A higher performance V8? Maybe a tweaked exhaust and a cold air intake or other similar light mods to bump the power by, I don't know, lets say 30 hp over what it would normally have? It could happen. Then again ... you could do the same thing to an LS3 today (and I believe that is the 2nd most popular engine proposal for the Z28, an 'enhanced LS3'), then do it again later once the DI engines come out. No need to wait for the DI engines if thats the formula you want for the Z28s engine.

Oh, and that TT DOHC 3.0L V8 makes no sense at all for any application. A similar V6 will definitely be lighter & more efficient. A NA V8 will be more powerful & cheaper to build (and in all likelihood, lighter & more efficient as well). I suspect its just a rumour tossed out there by someone trying to have some fun with the enthusiast community.

With the C7 the DI engines are suppose to debut. that will be a 2014 MY so 2013. As what I'm honestly proposing is going to be a bigger displacement over the base V-8 in the camaro. we honestly need 500+ NA. DI is going to be cheaper to get there. so it's not just a cold air intake and exhaust mod. remember we've only been talking about the engine choice. not suspension and other things. I will be honest that it may be a stretch for someone to think along these lines, but it isn't that far off from being a reality.


I agree about the TT 3.0 v8. that's just the rumor mill for the vette talking right now. until it actually does exist i won't believe it. A TT V8 could possibly make reliably 450 which is more then the current ecoboosted ford. off setting weight and efficiency. I just don't see GM going with a TT setup. They played with a turbo setup before and the most recent being 4 bangers. turbo setups are complicated and would be a nightmare for warranty work.


ZL1 2013 model.
earliest a z28 could honestly be debuted 2013 as a 2014 model. same year as the vette C7. DI could find its way in. just like the people claiming the LS2 was going to be the SS engine and GM went and surprised them with the LS3. it is possible.

We've been surprised before, even way back in '67 when the 350cid made it to the Camaro a year before it went in the Vette! I'm thinking we could see a new DI engine if the timing is right or we may see an LS7 if the timing is not good for DI. It's hard to say what they will do, I just hope that they do it right regardless of their choice.

I have faith they will either way. but if all pans out for the vette the timing for DI is about right if not perfect.

I'd rather wait for the lighter Gen 6 Camaro/Z28 with DI V8. I don't see why GM should even worry about a Z28 now. Yes, it would be great to have competition for the Boss , but I want no compropmises and that to me means less weight. Don't get me wrong, if GM makes a Z28 for 2013 I'll be really happy to see it but I'll save my money another two years for the real Z28.

One important clue to the next Z/28 could be keeping an eye on the next CTS coupe. The current CTS is almost the exact foot print of the Gen5 Camaro. Just like the Firebird was the F-body cousin to the Camaro, the CTS coupe may be it's older cousin by a year or two.

CTS is going to be getting bigger. Camaro is going to be getting smaller.
