Is the G8 6.0 engine exclusive to Holden or is it also installed in other GM products? How tested is this engine?

This 6.0, the L76 with AFM is unique to Pontiac G8. Holden will get AFM once production capabilities catch up (can't find it now, but I recall the engine might be built in Mexico) it should be the standard engine for Holden.

It is most closely related to the L76 without AFM but with VVT used extensively in Chevy/GMC full-size trucks, including Silverado, Avalanche, even the new Tahoe/Yukon hybrids.

The L76 has been in Holden's Commodores since 2006 (VZ). Only HSV used the LS2. As for US models, the G8 will be the only vehicle to have it. But, considering that it is a Gen IV small block, it has a wide variety of parts & pieces to improve performance (if you want). As for being tested, only the AFM would be a concern to me. But, even that doesn't seem to be a big concern. GM has been using AFM on the 5.3L (Gen IV) LS4 in the Grand Prix GXP & Impala SS for 2-3 years. No public recalls, no major media stories of problems for the AFM system.

What is HSV?

When I was a kid my dad owned a '71 Caprice, it had a 400 V8 engine. Anyone know where I can find specs on this engine? I remember that Caprice really hauled a$$ and am courious how much hp it's engine produced. Both the '71 Caprice and the G8 weigh about 4000lbs.

What is HSV?

Holden Special Vechicles

Think of it as Holdens AMG, M, SS performance divison where the very best goes into these HSV units. More power, more features.

Looks like probably 170hp but possibly 260.

...well then the G8 GT is a rocket.

Basically. I thought my dad's Grand Marquis with 190hp was fast.

Just watch out of Evo/WRXs.. unless they don't know how to shift.

I did a roll on race with an STI on highway 101 in cali...he jumped me ..about a car and half...since i wasnt fully commited for a half second.....we caught him...and passed him in about 6 seconds...ill guess at 110...and pulling hard on him...than i lifted after passing him....

We had a 1970 full-sized Caprice station wagon with that 400 V8 4-bbl and it was a dog.

The 396 4-bbl in our 1968 wagon was much stronger.

and http://en.wikipedia.org/wiki/GM_Small-Block_engine 255hp @4400 rpm, 390 lb-ft torque @ 2400 2-bbl Rochester carb. By 73-74 output dropped to 150, took a 4 bbl to hit 175. It was the only way they knew how to up the mpg and reduce emissions on land yachts back then.

It may have felt fast due to soft suspension and nose lift, but I'll bet it had to work real hard to come close to 10 sec 0-60. The GT is nearly (but not quite) twice as fast.

I thought the L76 was made in Canada along with the LS1/LS2/LS3 family line. Not sure. Saw a High Perf Pontiac article couple years back (pre L76)

The "Lord Vader" Impala SS of the 1990s had 260 HP, which was considered wicked at the time. Horsepower went through the roof in the 21st century. Before then 300HP was rare. Nice piece on the Impala SS in the most recent Automobile magazine. (one with the POntiac Solstice Coupe on the cover)

Needless to say the G8 GT would smoke Vader's ride, unless he traded up for one himself.

SRT8 KLR??:sneaky:

The history of the Gen III and Gen IV 6.0 liter dates back to 3/4 ton GM trucks.

The original production 6.0 was an iron/iron engine rated somewhere around 315hp/355lb/ft of torque.

From there the general made a few changes including aluminum heads and higher performance versions (LQ9).

From there it made its way over to the Vette/GTO/TBSS in the form of the Gen IV LS2. This was primarily a 6.0 liter block with LS6 heads.

From there you get the new L76 which is basically the 6.0 liter block with L92 heads/intake and AFM.

Obviously the tuning and electronics have changed over the years, but the basics are the same.

Best,

Dustin

Actually, the heritage goes back to the Corvette. For the C5 Corvette ('97 model), GM wanted to continue the legend of the small-block V8. But, their basic architecture wasn't as capable as GM wanted. The Gen III (LS1) came out as a radical way of thinking for OHV engines. All subsequent GM small block V8s came from this design. LS6, LS2, LQ9, L76, L98 (Australian version of the L76), even the LS7 all owe their success to the LS1. This is one of the reasons that the Corvette gets all of the attention when it comes to new engines & other technology (MRC suspension).

I was merely giving him the production history of the 6.0 liter.

Certainly all Gen III and Gen IV engines trace their roots back to the LS1.

This is a bit off topic, but when did we switch from cu. in. to liters? In America, we still have miles per gallon and gallons of gas. We need X quarts of oil. We drive 100 miles per hour. We have 385 lb-ft of tourqe and 361HP, yet instead of a 376 cu in engine, we have a 6.0L. Marketing at its finest? What gives?

Mostly marketing. All the foreign makes use liters instead of cubic-inches.

When it comes down to it a 6.0 liter engine sounds ton bigger than a 2.0 Honda.

It should be measured in gallons, 3.79 liters. Hondas, then, would half a half-gallon, normal engines would be around one gallon, and big engines could be around 1.5 gallons.

ANDALE ANDALE ARRIBA ARRIBA!!

GM builds all over the world, specially North America,Central and South America.:coffee:

g8s stock are just as quick as the Srt8 chargers...faster than the CHallenger srt8 oh and will be adding tons o kills of rustangs :)

TrickStang37 ... curious how trick ure stang is....
IF memory serves me correct...IBM is still the only thing out on my favorite testing ground...BAILEY ave /raceway correct? run whatca brung??

From what I read it is basically as fast as a SRT8 Charger. But I say a 4.8 sec 0-60 time for the Challenger, which should be somewhat faster than the Charger.

As for your standard Mopar hemi, they haven't got a prayer. Ditto Mustang GT.

And of course the most fun of all, smoking 99% of all 5 Series BIMMERS.

The switch to liters of displacement was in the early to mid 70s and was a marketing gimmic to hide the fact that engines were shrinking drastically. People weren't altogether familiar with liters, and how they compared to cubic inches. So, GM advertised a 5.7 liter engine (350 ci), and it slipped under the rug that the 454 big blocks, etc. were gone.

The original 64 GTOs I believe were the first US cars that advertised their displacements in liters in the call outs.....6.5L in the GTO crest on the front fenders. DeLorean felt it gave the car a more "European" flair.

As an aside, 6.0L = 366CI not 376!

Sorry guys.. It is actually 5.967 Litres = 364.3 CI. It had better be other wise I will have to change my id!!!!.

364 CID is correct. The 6.2L is 376 CID, in case anyone was curious.:D

You know I thought it was 364 initially as well and then that silly metric conversion website had me second guessing that I was rounding wrong!!

I think you have forgotten that the ratings were changed from gross to net so dropped by a large factor in the early 1970s with little or no change to the engines; and while the emissions laws were tightenng I don't think the poor mpg figured much in US carmakers' priorities (or buyers' expectations) on these truly leviathan sized cars until the OPEC embargo hit in late '73.
But all the same I love them desperately - the last cars built where style and size were as important to the designer's brief as function and performance (in fact probably moreso).

First time I've heard this theory - surely wasn't it that the US was thinking of converting to metric in the late 60's and early 70's just as the rest of the world had or was doing? It was perceived as a modern and correct thing to do, "international" even. Australia had gone metric by 1975 (we even went to decimal currency - a.k.a. dollars and cents instead of pounds, shillings and pence - in 1966). Our 173/202cid six-cylinder became 2.85/3.3 (and 253/308 V8s became 4.2/5.0) at the release of the LH Torana in early 1974 and the following September the new HJ series Holdens followed suit, but there had been smaller 4 cylinder engines used in the Vauxhall origined Toranas using the then common cc (1200/1600 later 1350/1750) used in Britain. My 1973 Monaro has speedo in km/h (with an inset ring of MPH markings) and odometer in kms, but I think by HJ only metric was shown. (I think there may have even been an earlier interation where the metric was subservient to Imperial as another in-between step).
I remember reading in a contemporary American magazine that the 1976 Chevrolet Chevette was referred to as the first (of many to come) US-built metric car although of course much of the design was from the European Tcar.
Oh, and it's litres btw LOL!
