I'm just going on what everyone here says. The Gen V will have 5.3(or 5.5) and 6.2L versions. We have those displacements now for Gen IV V8's. Also everyone seems to say the 7.0L is dead after the C6. There is no reduction in displacement, other than the 7.0L, and 6.0L going away. 4.8L will also go away though too.


With what engine though? Supercharged 6.2L I suppose

I'd love to see a 530HP Twin Turbo 5.3L V8 in the Z06

 

 

There are all sorts of technologies that the Gen V might have - DOHC for example. I don't know what might make it into production though. A normally aspirated version of the 6.2 of over 500 hp is certainly possible.

There are also rumors of a SC'd Gen V as well.

 

The original quoted article stated the Gen V engine will retain the OHV layout.

 

It's been designed for both.

But I also get the impression that the early Gen V's will look very, very much like the Gen IV's.

 

I guess I should have been more clear.

5.3 has always been a truck displacement except for the short run of W-bodies a few years back. I don't see any reason why a 5.3 would end up in a Corvette or any other RWD coupe/sedan. I'd like to see the LS7/7.0 stay but it doesn't sound like it will.

 

One is certain. The question is, will there be more than one?

There will most likely be a Z06 and ZR1. GM needs the ZR1 to stay a production model for racing, and the developments of the ZR1 & Z06 have benefited far more than team corvette over the years. The Z06 will remain the 'top dog' Corvette as it has, with the ZR1 remaining a 'collectors item'.
The real reason we want this being you could go buy the parts from your GM dealer to build an LS engine twin turbo kit in about 5 minutes.

 

The only reason to us the 5.3L in a car would be if that engine achieved LS3 levels of HP. Gen V will have DI and a host of new technology. Ford is getting 411HP out of a 5.0L, Hyundai has a 429HP 5.0L coming out. If the 5.3L can put out 430-440hp while getting better mileage than an LS3 then I see no reason why it couldn't be used in the Corvette or Camaro as a base V8.

 

I underlined the key phrase there. I'm not yet convinced that a smaller displacement automatically means better mileage, there are so many other variables that go into it.

Is Mustang's 5.0 getting much better fuel economy than the LS3, either EPA or in the real world?

 

Not that I've heard/seen. The 5.0 is putting out less horsepower, carrying around less weight and is still not beating the LS3 in real world fuel economy (real world numbers being the only ones that actually matter).

 

How much higher would 5.5l Rev to, than 6.2L?

 

Let us not forget that there is historical precedence for a 5.3L in the Corvette and other RWD sedans/coupes. The gen I small block 327 ci V8 displaced essentially ~5.3L.

 

Direct Injection and what other tech the Gen V has that the LS3 doesn't is what will do it. Real world doesn't matter. It is what the EPA and CAFE numbers are that count.

 

Actually classic 327ci V8 translates to 5,358 cc or about a 5.4 Liter V8, not 5.3 Liter. The 5.3L is the current LS4 with is actually 325ci or 5.328 cc.

 

I will never understand why people like lower displacement.

It's assinine. The engine weighs MORE, the fuel economy difference is non-existant and it makes less power.

Lose/tie/lose.
