N.A. Z/28 only way to go
IMO the z/28 has to stay N.A. for track use, the camaro team needs to keep the LT4 out of the track car, there way to limited for the track, they don't like heat at all, was at the race track this weekend and 3 of 3 15-16 C7 Z06 went home on a flatbed tow truck from over heating, most did not go past the 2nd set of runs, don't do this to the Z/28.
Still hoping the go with a smaller C.I. motor that pulls to 8500 RPM, that will help on Lang tracks, and get the weight down in the 3500lb range. |

If the Z/28 is n/a, I bet it will be something along the lines of the LS6. Better heads, hotter cam, better intake manifold. The LS6 saw a 15% increase over the LS1. That would put the LT6 at 530 hp.
That should keep development costs down as well. Put the extra money into the light weighting. Imagine a Z/28 making 530 hp, 480 tq and weighing 3600 lbs.

The Camaro platform does not seem to suffer from the issues that the Vette platform does if the media track rides of the ZL1 are any indication.

For track purposes, I would take NA over boost any day. Not due to the over heating "issues" which like Eric SS said, they did MASSIVE amounts runs without holding anything back @ track for the press and not a single overheating issues but you want NA for "instant" torque and power delivery over boost to get you out of the corners much faster. Boost will help more on straights but it's not like the car will have a 2.0 engine where it suffers on straights so with enough power, it won't be an issue and will definitely be a BEAST on track.
I do like what Bhobbs said. That would be amazing! LT has a lot more potential than the LS did, so I can even see it being 560 hp and 500 tq easy and weighing very little. Not to mention that the gen5 z28 did have a "rotofab" intake on it and not the klenex tissue panel air filter like the gen6 SS / ZL1 so they could easily start it off with the CAI one which right there is a 15+ hp to start off on top of the 455! Cams, intake manifold, heads, tri-y headers even stock with a little bit of a more aggressive factory tune, greatness can happen! |

I like NA for the track too, but your comment about "instant torque" isn't an issue with a roots blower. The boost is instant, there is no lag like with turbos or centrifugal SCs.

Naturally aspirated isn't the only way to go for fast track times.....but it probably is the best. Should be interesting to see how this plays out.

I want to see an N.A. 5.5L in the next Z/28. Back in the day I had some playtime in a 1969 Z/28 with the crossram dual 4bl 302ci V8. What a quick reving high rpm motor.

I for one like the idea of an N/A Z/28. But when it comes to lag, twin scroll turbos and belt driven superchargers do a good job of mitigating that.

I'm curious to see what they do with it as well. There's no way it will have the problems that the C7 does. The C7 has everything stuffed into such a tight package. Even the 2014 and 2015 Z51's without a blower overheat on warm days with spirited driving on the regular road. And they're overheating in both the transmission (esp. those that got the A8) and their oil temps. I don't think the Camaro will have that problem if they add a blower...there's more room for everything to breathe.
I think the real issue with adding a blower is screwing up the weight balance. The weight of the SS is already skewed to the front of the car.

Very true, definitely NA isn't THE only way to go. I really am curious of which way and what they will end up going with. |

Building the new engine off the LT1 block and heads will help keep costs down.

Yeah but if 500 is good 530 is better.
