I was gonna say any GM plant that's not building anything Silverado adjacent

But right now, all of them :lol:

That is actually a good point. I wonder how the strike will screw up their preparation.

Have you put your order in yet?

Sharp looking Chevy.
Nope! I was planning on a C7 Z06 but those ('15-'16) are in spitting distance of a base C8! I want to make a move by summer tho! If the C8 kills the resale on Z06s I might grab one of those for a couple years! But as of now I really leaning towards skipping the C7 and getting a slightly used C8.

Can they make any Corvettes right now?


I just saw that GM is not taking orders on ANY cars as we speak! I'm thinking they figure the Walk Out will be over in time to start building C8s! They're cutting it close tho!!!

Maybe that's why someone said the first 3 years of production are already pre-ordered. Because they assume the strike will reduce production to 3 cars. :lol:

C8R confirmed to have a 5.5L flat plane DOHC V8. Around 500 hp depending on BOP. It'll have to be in a road car. Wouldn't be surprised if the road version is 6.2L or 7.0L with 600+ hp and then they supercharge it for 700 hp.

Wonder what it's gonna be based on. Blackwing is too small. DOHC heads on the LT is gonna prompt a Lotus Europa rear end

From what I've read the street car will have twin turbos.

The Corvette Team says the new motor is not based on the Blackwing but we shall see..........

Everyone watched Matt Farah's video of him driving the C8 and said he was short shifting.  Pooprods just don't rev very high, which is very counter intuitive to every other mid engine sports car.  I'd love for them to put a high revving DOHC in it.

Everyone is shocked when I tell them I set the redline on my SBC all the way to 6500. :lol: That's what the cam and intake are designed to make power up to, though.

That was short shifting even for a poop rod. He was upshifting like 4 times on a short straight. Something was up

Race car only, or will there be a street version?

It's the valvetrains you gotta watch out for.

Valve float is just a built-in rev limiter.

Normal. It's a street engine.

"Street engine" can mean a lot of different things.

I thought you had a 3/4 race cam with higher compression pistons and, hopefully, stouter bottom end.

Yes, some shift testing by a journalist.

Custom grind Erson roller cam to match the Dart heads and Edelbrock Performer RPM intake. Good stuff, but not a racing SBC with a single plane intake and crazy cam profile with no manifold vacuum and crappy idle.

The crappy idle is what makes it sound special.

He was short shifting.  I think he even put in his video description that he was short shifting because it was his sighting lap and the very first lap in the car, cold tires, etc... so he was taking it easy.

Modern SBCs will rev to 6500.  More for certain versions (like the LS7).  I don't think he was taking it past 4500.

The Ford Voodoo is sorta interesting but still can't outperform the ancient LS7, plus the Voodoo is bigger, heavier and more complex, because it was chasing revs. IMO you have to bump up to the $190k 911 GT3 RS to find a better N/A motor (and then we'll see how durable it is) than the GM LT2.

I'm glad that Corvette is developing a proper race engine.  Not sure if Ford will continue racing the GT, but it should be fun to see them compete against each other on a more equal footing.
