Reuss was cornered at the very end of his interview on Autoline Detroit, today, and would NOT deny the possibility of a "Zora".
http://www.autoline.tv/show/1901?play LF3 to LF4 included one upgrade that would certainly be worthy of consideration on an "inspired" rev-crazy LT1 - ti rods, ala LS7. The rest of the recipe for 500+, as mentioned here and on GMI, has already been tested... Green-lighting it, at the risk of development AND potential assembly costs vs. LT4 is where the program would live or die. I don't think there's a big market for another (single version) Z/28 @ $75K when the possibility exists for a mid-$50s (Base) GT 350. And, quite possibly, a weight-conscious LT4 version just might handle (no pun) BOTH a GT 350 and the potential GT 500. Time will tell... |

They really can't make excuses for not making another engine when Ford has done it, and in the second model year.

I can imagine a 6th gen Z/28 having comparable performance to the 5th gen Z/28 at much lower cost, for a whole host of reasons. |

The 1LE is 9 seconds faster around VIR with the same engine as the SS, mainly due to lower gearing and wider tires. A "special" tune and a few tweaks to the LT1 and a C6 1LE should be pretty quick on the road course, probably worthy of being called a Z/28.

If GM and Ford were working on mid engine cars, would we have seen a mule or two running around my now? Especially with Ford supposedly returning to Le Mans next year. Quote:
The only comparable engine from the Camaro, if not GM as a whole, would be the LS7 and maybe LS9.

I for one would love to see the Z/28 stay N/A while the next ZL1 should use the LT4...that's what makes the most sense to me.
I also agree, that it seems pretty damned easy to get around 500 HP out of the current LT1. But GM has already stated that they started with an N/A engine for the Z06 but couldn't hit power and emission targets so they went with forced induction. So does that mean our dreams for an N/A LT(whatever) are already dashed? Or was GM going for ridiculously high HP (550 - 600) on an N/A V8 engine and just couldn't do it while staying within emissions? I'm fully aware I don't understand all the strict guidelines and laws and this and that GM has to abide by when developing an engine, but it just seems too easy to me to pick up another 40 - 50 HP in the LT1 and call it a day. Can't see why it wouldn't hit emissions targets either.

Mules get disguised well and it's possible Ford dropped a drive line into the existing GT. Aero/body being developed in wind tunnel still. I can't wait to see Ford's flat plane in action. I'd also like the Z/28 go the same way, get even closer to a race engine.

The issue with GM using a FPC is the small block needs more displacement to make power. The engine would vibrate way too much. I read that Ford had some serious vibration issues early in the GT350 development and its a full liter less displacement.

When considering GM vs. Ford engine development, here's a small-but-significant corporate consideration: GM's current across-the-board drivetrain warranty goes to 5 year/100,000 miles, while Ford's coverage ends at 60,000 miles. Although, typically, ultra-high performance engines don't see the annual mileage of more pedestrian versions, there IS a standard that must be met.
The Chev Performance Parts crate engine program enjoys a relaxed warranty coverage (as much as 3 year/36,000 miles if GM dealer-installed, or 12/12 if hauled home from over the counter, generally), which affords them the opportunity to create hopped-up LS3s rated at up to 525 hp. (that may NOT be 50-state emissions-legal and are NOT subject to potential CAFE concerns) with MUCH less concern than if those same sorts of engines were installed as OE and covered by GM OEM warranty. |

MY point is, a high-revving special-build engine that will be assembly line installed ISN'T simply a matter of mix-n-match components and "call it a day", unfortunately, as MUCH as I am a strong PROPONENT of exactly that recipe... Reality vs. perception/wishful thinking. Having said all that, if there's a sensible, solid business case (perhaps involving more than one vehicle line), the chances improve greatly. CAN they? Of course they can. WILL they? Stay tuned. Z/284ever's efforts are to be commended. Perhaps Janet can/will share the results of this thread (and the one on GMI) with her associates, as well. Just in case they've missed out on the passions shared... |

GM has "outlined" the Camaro with the 5Gen. The cards are on the table from Ford. Why would GM change direction now? To change now would be very very foolish based on the Camaro's success.
