GM announced today that the new LS7 7.0-liter OHV V-8 will be capable of running up to 7100 rpm, up from the 6600 rpm in last year's Z06. Engineers are showing that multi-valve overhead cam performance is achievable with a two cam-in-block engine. The Z06 can now reach just over 60 mph in first gear, assuring that the 0-60 times will be under 4 seconds and the top speed will be over 190.

      15 comments and not one mention of the 302DZ. what is the world coming to?! it was the high-revving small block Chevrolet produced in the first generation Camaro. it was spinning 7500-8000 in *1969*. i was under the impression this was a decently well-known motor. but apparently not. "Chevrolet put a 283 crank with a 327 bore and solid lifters hence creating a 302 cubic inch block w/4" bore, 3" stroke that would rev 7500-8,000 RPM on the bench." a small block V8 hitting 7000rpm must sound pure awesome. while that is impressive only in that it was in 1969 ... and it was technically only a 5.0L V8 engine... it's really impressive to me to see a 7.0L V8 going over 7k. people really need to do some thinking to understand exactly what that means. 7.0L and 8 cylinders at 7100rpm is damn impressive for an OHV. i mean... i would *expect* a 1.5L V12 to hit 14 grand all day long. it would *have* to. i've seen it referred to as the DZ302 and the 302DZ.

      I agree, redline is useless as a performance stat. The thing that makes the Z06's redline impressive is the massive amount of torque the engine makes. By comparison, an S2000 at 9K RPM is positively anemic. What does it make at 9K? 100lb/ft? Still, like 010111 said, getting a 7L OHV engine spinning at 7K RPM is very impressive.

      60 in first is nice though, the better question is how many gear changes to get to the quarter mile? and its two bad the car already handles like a rollercoaster car, i'd love to hear about handling improvements too...

      "Posted May 4, 2005, 2:49 PM ET by Locky GM hasnt break none...lets compare apples to apples, v8's to v8's shall we?. lets look at the MUGEN MAX specification..... oh lookie it revvs at 95000RPM and its a v8 as well. Honda Mugen LM (Legend Max) Engine type: V8 Naturally Aspirated Displacement: 4.0Liters Horsepower: over 500ps Valvetrain: 32 valves, DOHC Layout: 90 degree V8 Naturally Aspirated Displacement: 4000cc Horsepower: 590hp / 9500rpm torque: 383lb/ft / 7500rpm" Look at what you are comparing, a 4.0L v8 vs 7.0L v8. and the 4L is DOHC to boot!!! you should really think before you post. This is topic is about a 7.0L v8(BIG DISPLACEMENT), with an OHV configuration (ONE CAM NOT TWO or FOUR, WITH MANY MORE VALVE TRAIN COMPONETS THEN A OHC CONFIGURATION) spinning over 7000rpm!! in a production vehicle! its amazing!

      "Hell most import DOHC engines can rev to 8k rpm with ease" Leave ferrari out of it and name some 8k rpm V8's Infact the only 8k rpm motors I know of come from: Ferrari, BMW, Toyota, and Honda, Subaru has the 555 which also spins to 8k just not here - and that's pretty much it I think. Not all are 4 cyl's either there are some 6's and 10's in there but there aren't many 8k V8's. None the less I don't know a single engine that can rev above 7k that I'm not impressed with OHC or not..

      Who cares about redline? Koenigsegg has a V8 putting out 806hp and it redlines at 7600.
      • 10 Years Ago
      I can't believe these S2000 lovers believing redline is everything. Why not compare a sport bike reving at 14 000 rpm? Hey, add in an F1 car at 19 000 rpm. Now start to factor in that you have to be a midget to drive the S2000. Don't forget that if both occupants weigh more than 150 lbs it won't have enough torque to pull you to 60mph in less than 10 seconds. Let's compare apples to apples. Not apples to lemons. The Z06 is definitely world class in many aspects, and the fact that they are the first to push "old" OHV engine technology to the limit is impressive. The fact is, no one has done it before. End of story. Can't wait to see what's next. The Z06 is the biggest automotive bargain of the 21st century and will likely remain so for a very, very long time. Bring on all who say otherwise.

      Uhh.. 7100 RPM is an accomplishment???!?!??? Hell most import DOHC engines can rev to 8k rpm with ease. The cars impressive no doubt, but not because it can rev to *gasp* 7100 rpm.
      • 10 Years Ago
      It remains to be seen whether the handling in a Z06 approaches the levels of Porsche or Ferrari. It would be interesting how Dodge responds and whether they introduce a new car to compete against the Z06 or whether they re-tool the Viper.

      Sounds great. They've managed to achieve what my '91 ZR-1 has done for 15 years. As far as rpms go, I used to hit the 8K mark consistently in my old '74 Mazda RX-4. Of course, at 130 mph that thing felt like it was looking for a new trail to blaze somewhere off the highway. As to the ZR-1....at 190 it's loud enough to remind you what driving a super sports car is all about, but it hugs the road and still wants more. I'm looking for my first C6 to play with. ;)

      The key here is that it is a Overhead Valve 7.0-liter V-8. It mates the low end grunt of a big displacement engine with the revving range of a smaller Overhead cam engine. That is a big accomplishment.
      • 10 Years Ago
      It's an overhead valve...not a OHC. And not very many engines except for exotics and four-bangers reach 8K with ease. At least not more than once.
