I know , think this car, if it lives up to the hyp will do it for me on the Gen6 camaro line, or they have to make a sub 7.00min at the track car for me to come back and get 4th car.

Coyote Red in sport mode

I'm over building a & road pony and then "trading up", as I value my work. I built a Cyclone to be track ready then buy a 16 GT for better motor. That's my last trade, if I hit the lotto I'd buy a GT350, if not, I'll build my own project, thank you!

found the link hope it ok to post.

That car is not spinning anywhere close to 9000rpm

C7.R does damn well in competition with a 6000-some redline.

Typically, high torque engines are larger displacement, and have a lower relative redline. And a low-torque engine needs to spin higher to make up the performance, like the Voodoo engine in Mustang.

The LS7 was that "sweet spot", balancing high RPMs, with high torque. There hasn't been an engine since then that could do the same sort of thing.

You'll rarely find both in the same package...would be wicked if this "Spin Tron" was reliable.
It's not really the engine size to powerband relationship, it's the pushrods vs dohc relationship. Dohc is better in every way to pushrods in regards to powerband.

It's not the powerband that makes the small block gm so legendary, certainly not.

It's the efficiency, cost, weight, size, reliability, and total hp. If you factor all those in you could argue it's one of the greatest motors ever created. You take the same size motor and make it dohc, it will wreck the small block gm in the power department and power band.

Also having owned a coyote, an l86, and renting a camaro ss, I can say without a doubt the coyote is the superior sports car motor in regards to powerband. The only reason the lt1 works so well is because the chassis of the camaro and vette does an amazing job of putting all that torque to the ground. The difference in traction between the mustang and camaro and what happens when you put your foot to the floor from a standstill is just amazing. The camaro pulls so much harder from a stop. Get out on the open highway though, and the mustang feels just as fast, by comparison it feels like the camaro has a truck engine and completely runs out of steam up top. IMO best mods you can do to the lt1 allow more breathing up top get rid of the downward torque slope from 4500+

Coyote swap into a Camaro sounds like what you're getting at :P

GM developed a LT 7.0L DI setup said to rev like the LS7. But could not get the power goals set forth. Think it was like 525 with just a bump in manufacturing cost over the LT1. So they do have it. Also the 5.5 ish LT Proto type was like a 8K +RPM with very aggressive top in power but lacking in low range. Whether it's true or not was said to be like an old 4.8 stroke with the 7.0 bore. The 7.0 heads let it breathe really at high rpm's.

Sorry but this has already essentially been done quite a few years ago by the NASCAR cup guys. Most if not all the major engine shops had 10,000 or 11,000 RPM valvtrain programs (they would get way into the 9,000's on race day before the rules backed them down). I'm all for RPM but the reality is more RPM translates into more maintenance 10 out of 10 times...

What about High RPM on the V6? If the turbo is going to be ignored and the ecoboost stang is getting more torque, why not commit to a rev-happy six and drop the four cylinder altogether? I've heard so many reviews and owners praising the V6's current feel and sound. Higher RPM would improve upon both. It currently redlines at 7000, and makes 335hp. Upping that redline to 8000 and upgrading a few things like the intake and throttle body would make for one heck of an engine. That could be making 375hp, which is as much as a Challenger R/T. Imagine an 8000 rpm engine with the ten-speed and NPP exhaust... WITH A 1LE PACKAGE! That's a BMW beater.

The V8 should stay OHV and torqey, just the way it has been for over 55 years. You cold start an LT1 and get goosebumps every time. It sounds so good and I've read that it feels good too. A higher redline on it would take away from the brutal low rpm torque that Chevy Small blocks are known for.

I've seen the video a few months ago when a fellow engine builder called me and we laughed.

What they really need to focus on is if the Head can also support the FLOW at such High-REV rpms.

You guys really need to stop by some of the NASCAR-level engine builders some time. High-revving SBC's are and have been the staple in both Busch Car and NASCAR Racing for years.

What the video doesn't show you is the "Dark-Work or "secret" stuff they're putting out for the current U.S. Teams.

There's behind the scenes "R&D" everyday, when U.S. race teams have advanced to something new, their old trick stuff trickles down and becomes the latest New stuff. Thus a new youtube video is born...lol

If you want to have fun like I do just try to pull out HP gains WITHOUT modifying your Factory Stock Car. That takes tenacity, more skill, and thinking out-of-the-box than just buying, adding, buying, adding parts.

IMHO, current today's ZL1 fast runners are only using existing "Dark-Work" and rarely inventing new break throughs.

Btw, Doesn't anyone remember NHRA Stock-based Classes and what "Grumpy" Jenkings did with a SBC?

Btw, one of Grump's high revving SBC was only a 331cid with OVER 2HP BHP PER Cubic In OUTPUT with a Cast Iron Factory Block.....lol

More maintenance, probably, but a street driven car is not going to be buzzing around at 9,000 rpm all the time. If we drove around at redline in anything, I'm sure we'd see more problems.
