I like the idea of a zippy small V8, along the lines of the original Z28. As long as it still gets pretty good torque, I'm all for the smaller, higher tech Gen V.

I like the idea of a gen5 engine. But I don't want to give up displacement.

Gen V. hands-down, no argument.

There is no replacement for displacement, but we've got to shift gears, so to speak, and shrink the engines. We can't very well start offering 427's as the base V8s in cars, and a few years later put 572s in the base car, etc...It has to be kicked down somewhere. That's where the GenV's come in.

Gen V please, any displacement. If they were to make it a 5.7L . . . the streets will once again fear the chevy 350 small block. Should make 450 hp or so, depending on tuning. With mileage possibly breaking the 30 mpg mark.

That would be the ultimate F U to Cafe though! Add another 30 cubes of displacement every year. And measure in cubic inches too. 427 not 7.0, 454 instead of 7.4. Offer them with E85 though, use that 'little' loophole to take care of the enviro side of things.

I go with Gen V. Higher tech is a good thing for fuel economy and that needs to be considered in this day and age. I still want a V8 but I also need to able to drive daily.

Actually there is. It's called BETTER design engineering. The 3.6L V6 makes 300hp+. The 3800 V6 Camaros made 200hp. The replacement for displacement is...................SMARTS, smarts of the people designing the engine.

Just a question,

What happens when those same smart people work on improving the power and efficiency in a V8 engine. Is it possible to concieve that they can engineer a V8 that produces more power at the same fuel consumption of a V6?

All things being equal (including smart engineers), a V8 will produce more power than a V6, and a V6 will always be more fuel efficient than a V8.

Ok maybe not always, I guess someone could make a 700ci V6 that would consume more fuel than a 350ci V8

Gen V with smaller displacement, DI and maybe 3 valves per cylinder. And in top version put turbocharger on

ill take the biggest motor im allowed this car will not be a DD for me. so bring the power and luckily gas is a business expense for me so as long as we have gas available im happy.

I'll take as big an engine I can get; hopefully with a supercharger. It's just easier, to my understanding, to make more power with larger displacement. I can definately see the side of the coin where technology and smaller displacements have advantages, and I'm all for efficiency, but I can conceed a little for a lot more power. I just want the most hairy Camaro I can get from the factory; I don't plan on DD'ing the car, so I'm not too concerned about gas, although, I'm not Mr. Money Bags by any stretch.

I voted 6.2L only for the potential, in my mind, to make more power easier.

I went with the Gen V choice, but I'd be a little unsure about the 5.0L (conjures memories of the 3rd gens...not our proudest years, even if it is my personal favorite convertible).

as a rule of thumb, bigger displacement= more fuel consumption, more cylinders = more fuel consumption. But odd things can happen. It is possible for a bigger engine to consume less fuel. This happened with the Grand Am and the Alero for the 2000 and 2001 model years. The V6 got better mileage than the I4's, while making more power. I don't know how they managed, but they did. And they are an exception to the rule (but I like pointing it out)

If I remember correctly, a smaller engine can burn more efficiently because there is less area for the flame to ignite. It that's the case, the smaller the better, in terms of efficiency, however, with Direct Injection, it is my understanding that atomization of the fuel is more complete, therefore, more of the fuel is burned, producing more efficiency. I don't see a reason why a larger engine couldn't be as efficient as a smaller one, although, it would use more fuel simply due to it's displacement; right?...

It would consume more fuel due to more cylinders/more displacement, but then you have to factor in vehicle weight, CD (Coefficient of Drag), rolling resistance of the tires, etc. However, depending on how big the difference is in all those variables between the V6/V8 or the smaller/larger displacement (even using the same # of cylinders), you might get a return based on the bigger engine having more power and thus having to not work as hard to pull the weight around. Just my personal take on it.

Well, it could also conjure up '67-'69 DZ302 Z/28 engines which were 5.0L!

If you want to get completely technical with it, 5L = 305.11 cid, using that 1L = 61.022 cid, 4.9L = 299.0078 cid, 302.4 cid divided by 61.022 cid gives you 4.9555897 L, so round up or down?

That was what the DZ302 did best, built for racing. Those GM boys were sneaky back then. How about a Corporate order special car with a 427, could call it...Oh, I dunno, anybody have a good name for it? ZL2 hood, dog dish hubcaps, no badging, hmmmm.
Might better just build a few tho, in case it doesn't sell well, 69 cars would be a nice round number.

Exactly right, my Sierra Z-71 4x4 ( 5.3 V-8 ) gets better gas mileage (22 mpg on flat highway) than my S-10 ZR2 4x4 ( 4.3 V6 ) which will never get 20 mpg on the highway, of course the 5.3 is a lot newer technology, but the truck is A LOT bigger, wider, taller, heavier.
