Well, the LT5 is now confirmed a thing....
Got an email from GM last night about the new ZR1 Corvette and it's new 755 hp LT5 engine...maybe there's hope for a Z/28 someday....

My personal opinion is that if they make a Z/28, I hope it has a high reving N/A engine in it, not the LT5. Hell, throw a slightly reworked LS7 in it and give it the ZL1LE wheels, aero, and a little diet. (It’ll never happen but I would be ok with that.)

Al O already said the Z/28 is an n/a car. If, and that is a massive if, there will ever be another Z/28, it won't have the LT5.

Well then sadly I don't think this fabled Z/28 is ever going to happen. GM will never get a NA engine past current and beyond emissions standards that makes enough steam to not be considered "slow" compared to the current crop of forced induction power plants. Sorry, NA is great...but forced induction is the road ahead. If NA truly is the only way forward for the Z/28, I think it died in 2015.

The emissions question really is a matter of startup emissions. And the big-displacement engines can't hack it on cold startup. Smaller displacement engines can....but you lose the power figure...so, the solution there is individual cam-phasing, and higher revs to make up the gap in power...but you're going to end up with a lower-torque engine, like the Voodoo V8 in the GT350, or any number of European engines. |

Z/28 will fallow the last gen, with more power and a new DCT TRANS, power will come from a N.A. motor. |

I still think the Z28 name is too important to just leave on the sidelines. Perhaps we get a preview of the NA motor from the C8 Corvette. I still think we see something when the car is refreshed. They have boxed themselves into a pretty good corner though. The SS 1LE is pretty close to what you might expect a Z28 to be. The ZL1 1LE is so extreme that it sets a high bar if the Z/28 has to out perform it. I don't believe it will get the LT5 though. I doubt the ZL1 gets the LT5 either. I think that one is Corvette only.

First is putting the LT5 in the ZL1 1LE chassis. Doing this and maybe adding a couple of other goodies like standard CC brakes and such, would make it the top dog in the line up. The second option is to put the LT1 in the ZL1 1LE chassis. Having the DSSV, the A10 available, and the body panels, would be enough to distinguish from the SS 1LE. This would also keep Big Al from being a liar and the Z/28 remain N/A. Interesting note about the LT5 is that it has combines direct injection with port injection. In this case, for the purpose of adding the fuel needed to run 13lb boost to keep the engine fed, but it will also help keep valve coking in check. Also have not read anything yet that the LT5 has AFM. |

Hot LT-1 in a ZL1 1LE Chassis would tick all the boxes for what many would consider a proper Z/28. It would be a serious track package, it would be the fastest N/A powered camaro, and it would be one hell of a package. Price wise would probably slot in between SS 1LE and ZL1 |

Personally I think that would be the perfect 6th Gen Z/28. Look how good the SS 1LE is, pretty much the 5th gen Z's equal in some aspects. Add that stuff to a SS 1LE and I think you would have one hell of a track pack

One of the common observations of the Z/28 was how it feels like it runs out of steam at the high end. Essentially the suspension and brakes outperform the engine. I would think the hypothetical thing we're discussing would suffer from the same sort of characteristic... |

After the SEMA show I had read that the Chevrolet Performance team is looking into possibly making a conversion kit to put the ZL1 1LE front end (bumper, fenders, hood) onto SS Camaro's. The DSSV suspension is already announced that it will be coming and as far as brakes go if I were to upgrade brakes on a 6th gen 1LE I'd just skip the OEM stuff and go right to Essex/AP Racing. It will save weight over OEM stuff and outperform it.
