For those that will buy one, the namesake of the car and to never read Bhobb's say Camaro is limited by Corvette again ..... I'm hoping for
"A new large displacement NA engine, serving as the successor to the LS7. Likely to put out something in the mid 500s".

I fully accept the possibility that I am wrong. I hope I am. A new 7.0 making 550+ hp would be awesome.

I really think if Ford hadn't come out with the Voodoo FPC engine especially for the GT350 the Z/28 would have been more likely to get the LT4. But because the Voodoo was so unexpected and has been praised so much by reviewers I think Chevy knows they have to step it up and do something different for the Z/28. Ford raised the bar and I think people will be really disappointed if there isn't something special in the works for the Z/28 engine.

How does everyone feel about the idea of overhead cams? I know they experimented with that on the 90's ZR1, but moving away from the cherished old school pushrod design might indicate the beginning of the end of the pushrod for GM performance

all good posts...
my guess is LT4 but on the other hand GM seems willing and capable of blowing our minds so who freakin knows.

Sticking with LT4 prediction....The game is for the fastest track weapon....That's heritage enough for the Z/28....FI's time has come. It's still Chevy/GM.
A brand new, very low volume, super-car unique engine still isn't in their mind-set. Maybe there is something in the skunk-works for a future mid-engine Corvette in a few more years. I think it's just too soon for the Z/28 if it comes out in the 50th anniversary year, which it should. A slightly bumped up LT1 for the Z/28? I don't think so. That should be saved for a 1LE or re-fresh SS upgrade. A very high hp N/A v-8? They tried that road and had to turn around. I don't think they will build an in-betweener engine that can't keep up with the ZL-1 just to say that it's N/A. The volume of Z/28 units just isn't/won't be there to justify a unique engine. We'll see, though!...Happy guessing! Last edited by 90503; 05-21-2016 at 12:45 PM. |

If it truly is N/A, I can think of four possible displacements, three of which are based on current production offerings:
1) 6.2 LT1 based - hotter cam and allowed to rev more 2) 5.3 L83 based - would have to be allowed to rev very high (same 96MM Bore and 92MM stroke as the L83 3) 5.7 using the 99.6MM bore and 92MM stroke for the GenV based LV3 4.3L V6. 4) 7.0 Same 104.8MM Bore and 101.6MM stroke as the LS7. This is the only bore/stroke combo that isn't currently in production Could the smaller displacement options be configure to allow the RPMs above 7000? |

I would much rather them stay with Cam-in-block, OHV configuration.

A 5.3 liter isn't going to make 500 hp. The 5.2 voodoo is DOHC and has to spin to 7500 to make that much power.

Just laying out the possibilities. Like the 5.7L isn't in production in V8 form but the bore and stroke are in the LV3 V6. My guess is either a 6.2 or 7.0 with AFM removed to increase RPM. |
