Interesting that they seem to be downsizing as well...

I really hope they don't put any of that DOHC bullsh!t on them, which is what I suspect they will do if they're decreasing displacement.

Ford went with the 4 valves per cylinder arrangement for the new 5.0. I would imagine that GM is doing something similar.
I wonder if any engineers thought about a canted valve arrangement at either company? Steve

Were'nt GM talking about a dual-cammed pushrod multivalve engine at some point - keeping the cams and the heavy stuff out of the head and down in the block?
Is this the first engine developed with Government funding, or have there been others? Lukeyson

I suppose HSV will be replacing their existing 6.2L with this beast for the entire HSV range as soon as they can, no doubt before the end of this year.

From my 'digging around', I believe that the Generation 5 (GENV) motor will be a direct-injected push-rod 5.5Litre V8 with 11.5:1 compression. Figures being touted for the production motor are 340kW/600Nm. The motor will debut in Corvettes next year but as a race only motor - don't expect to see it in production form before 2012. (Interestingly the race motor and the production motor will share the same block) Yes GM are 'downsizing' as they are subject to the same CAFE restrictions as every other manufacturer and these restrictions are getting tougher to meet each year. What GM/Holden/HSV will use in the interim - I don't know?

Will this 'race only' engine pass emissions?

Yes, if you read those more "old school" magazines it will appear that way. If you read Modified Mustangs, Modular Mustang, and other newer magazines you will find a slue of aftermarket companies that produce all kinds of performance parts for those engines. There is a ton of support and aftermarket goodies for these engines. You just need to look in the publications that are more geared towards those engines, and the old stand-by's do not cater to those enthusiasts so much. Steve

as the ls3 and it's driveline is becoming unfeasable. maybe the cost of a torque tube is prohibitive.

It certainly seems that way. Shoehorning them into the RX series mazdas and the like is not uncommon if posts on other generic sites is anything to go by. Be interesting to see what the after market crate numbers are like. Just doing up the old windsor lump opened my eyes to the relative difference in price and range between the two rivals. Personally I prefer DOHC anything, but the LS motors have served me well, as have the Ford sixes, both of them uncomplicated. |

From what I can fathom, the LS3 gm/km betters Tier2 Bin4, equals the C0 and markedly exceeds the other Euro 4 requirements except possibly the THC, only because Bin4 doesn't have that as a variable? |

DOHC valvetrain configurations were all introduced around the late 1910s and early 1920s - Hardly 21st century, heck, it's barely out of the 19th century - as opposed to pushrod engines which came into being around about the turn of the 1950s. People were listening to Richie Valens. The multitude of OHC configuartions have been developed and improved over the last 30 years from where they once were, co-inciding with numerous fuel crisis. Pushrods haven't needed that degree of development.. ..but if you think pushrods have stayed the same since the dawn of time, you clearly haven't seen GM's LS9 (as one example). OHC & DOHC isn't a newer, more advanced, or overall superior technology as the common myths would have you believe. More complicated does not, by default, mean more advanced. In fact an old engineering adage says that the reverse is true, but that's just an old adage. DOHC & SOHC just have their benefits and drawbacks just as pushrods do. And there's a very long list of all different kinds of pros and cons for each, which becomes more accurate once you get more specific. Don't get me mistaken; I'm not flatout saying OHV/Pushrod engines are superior either, it all really depends on the application for which the engine is to be used, thats where the pluses and minuses for different valvetrains actually mean something - but I'll make it clear here that the area in which pushrod technology excels at at least the same level as OHC isn't exactly a niche. I don't want to take this off topic (it's already been flogged a million times all over the net, and in much more detail too), I'm just trying to make a very small point here - that OHV isn't antiquated or outdated. AB did it better. Last edited by Kamshaaft; 04-01-2010 at 04:58 PM. |

On a Corvette forum they are saying it will be released in 2012 for the C7 Corvette. I would have thought that timing would be about right for the all new Commodore which is supposed to be released some time in 2012. Until then, what will HSV run? I would have thought they'd just make the LS3 and L98 euro 4 compliant.

^How long do new LS engines normally take to show up on Aussie shores? I think from memory the LS1 was available in 1998 model Corvettes, and was available here a very short time after, but then it seemed HSV didn't get their LS2s until pretty late on. They really missedthe boat with the introduction of the XR6T at the perfect time for Ford.
But if there's one thing GM isn't bad at, it's bringing out new engines all the time.. ..and I can never wait to see what Ford do in response (when they do). It'll be really interesting to see where engine development here goes now with "Government Motors" over there (is that name actually legit, or just a bit of wordplay?? ). As someone said, this engine is the first engine that's come out under them, and it really bucks the obvious trend. But who knows how long it was in R&D? It would be a substantial period of time, I would have thought, and what goes up (displacement)must come down, I guess. *shrug* |

It makes me laugh that a lot of Ford boys jumped on the ohc band wagon in 2002 when the BA came out. If they were so convinced they would have been making a scene ten years earlier when pretty much every jappa and euro had ohc.

Also, VZ initially had the LS1 until Euro3 came into effect, then made the switch to the 6.0 L76. |
