Oh, but the internet is full of hope and speculation. It couldn't exist without it.

The issues for any Z/28 replacement is what would it's mission be and where in the hierarchy of Camaro models does it fit.

We can already expect the new ZL1 to be fabulous at the track, just like the Z06.

Does a Gen6 Z/28 need to be faster around the track than the ZL1? I think it does.

Can it do that with the LT1? I don't think so.

As speculated (by me

), the easy Z/28 paths are a 1LE with more chassis and brake (CC) work and light weighting, or a ZL1 with CC brakes and again light weighting.

GM showed with the Gen5 Z/28 that it needed to be pretty incredible and track focused. Mark Reuss changed that very late in the program as the Gen5 ZL1 was the Z/28 and my recollection was it was his leadership and direction that changed course. I suspect that he has not changed his mind and has again provided direction and leadership to create something even more special than the "easy Z/28 paths".

Me? I'm hoping the LT5 is an LS7 replacement. A higher revving 6.2L engine in the 520 HP range. Just putting the improvements from LS3 to LT1/LT4 should accomplish that.

I'm pretty sure Al O said a Z/28 would be more analogue than the 1LE and ZL1, so I take that as no MRC or eLSD.

As for the engine, I'm with you.

Im with you, but I was hoping for LS7 displacement. 427 is a manic number. Add VVT and DI, and rev it to 7000, it could be in the 550HP range. That would give it bragging rights over the Voodoo. Throw it in the alpha chassis, and the Z/28 will run circles around the GT350.

I honestly and sadly do not think Tadge is interested in making such an engine, and I don't know if al can get GM to spend the money in developing a high revving engine for the Camaro. When I think what GM may have been able to make I think of this article....

http://www.hotrod.com/articles/4-8l-...pm-ls-stroker/

They took an LS3 block (4.060 inch bore) and a 4.8L crank(3.267 stroke), with the result being a 5.56L engine making 607BHP. They don't have to go as extreme and they have the added advantage of VVT and direct injection. GM could likely take a 6.2L LT1 and push it to 7,000-7,500rpms making more then enough horsepower and torque to get the job done.

Or at the very least some salacious sausage

Here is another article for a high revving LS motor

http://www.superchevy.com/how-to/eng...ring-corvette/

This 388 cubic inch engine (6.3L) engine revving to 8,000rpms and making 725BHP, I do wonder if GM will see what the after market is doing and get an idea to do something similar.

Too bad we never heard any high RPM screaming in the 'Ring videos.

A big part of me expects the Z/28 to pack a supercharged V-8 engine, though we will see maybe soon enough.

That's the most realistic, but we can all hope it's not what happens.
