dcairns Posted October 15, 2002 Report Share Posted October 15, 2002 Try poking around this website http://media.gm.com/division/powertrain/index.html They have some specs and picture of the engines The standard 6.0 engine for a Silverado is the LQ4 Vortec 6000 The Escalade uses the LQ9 Vortec H.O. 6000 From what I understand, it is just higher compression and agressive timing (and resultant high octane gas requirement) that get the extra ponies out of the LQ9. It is also interesting that the LQ9 is made only in Michagan, where as the LQ4 is made in Mexico or Michigan. ========================= Vortec 6000 6.0L V8 (LQ4) 2003 Model Year Displacement: 5967cc Compression Ratio: 9.4:1 Assembly Site: Romulus, Mich.

dcairns Posted October 15, 2002 Report Share Posted October 15, 2002 Cast Iron blocks, Aluminum heads for both engines. What sounds weird to me is the composite (plastic) intake manifold . Link to comment Share on other sites More sharing options...
SilveradoKid Posted October 15, 2002 Report Share Posted October 15, 2002 and its a cast iron block, the SSR has an all aluminium vortec 5300... and if you look around THIS site, you will be able to find a great many facts about the Silverado SS, infact, Mervz was so kind as to make a thread that has ALL the specs for it! .... http://www.silveradoss.com/forums/index.ph...69d6624b465e155 Link to comment Share on other sites More sharing options...
PotbellyJoe Posted October 15, 2002 Report Share Posted October 15, 2002 Cast Iron blocks, Aluminum heads for both engines. What sounds weird to me is the composite (plastic) intake manifold . the composite intake is the new 'BIG' technology in an old design... Toyota uses it on is 1.8L engine and saw an increase of 5-8 hp in application. Not bad for an engine that only pulls 130hp. What happens is plastic doesn't transfer heat like the metal would and so you get colder air into the engine. Its made of a thermoset plastic composite that has an extremely high melting point, infact your block would melt earlier, so don't worry about it. ITS ALL GOOD! I am studying to be a plastic engineer, and i want to work in automotive applications, so not that i'm an expert, but the guy who wrote my books is, and he commented on them.... -Joe Link to comment Share on other sites More sharing options...
ssvette Posted October 15, 2002 Author Report Share Posted October 15, 2002 Wow guys now your talking the stuff, cast iron vs aluminum, thermoset plastic composite. Now this is the way to take a thread and run with it, Thanks guys!! Link to comment Share on other sites More sharing options...
dcairns Posted October 15, 2002 Report Share Posted October 15, 2002 Well, I had heard of the use of composites in engines for some time now, this will be the first time I have owned some, though. I was skeptical of the plastic radiator end caps on my '91 S-10, but one side lasted 11 years and the other is still there. I guess they would both be good if I hadn't been yanking the hose off a bit roughly . So progress may be strange, but not always bad I wonder how the composite intake handles the pressure of a blower? Link to comment Share on other sites More sharing options...
andythompson005 Posted October 15, 2002 Report Share Posted October 15, 2002 Just an idea of what a Whipple supercharger could do for the SS. On the media.gm.com site under concept vehicles I found that the Fox Racing Silverado also using a 6.0 V8 and a Whipple supercharger was claimed at putting out 420 H.P and 530 ft. lbs of tourque. Maybe with a supercharger the SS could become a Lighting killer????????? Link to comment Share on other sites More sharing options...
ssvette Posted October 15, 2002 Author Report Share Posted October 15, 2002 My buddy runs a supercharged Grand prix and it uses a roots type supercharger, it didn't use the composite. But it ran 13.7 with a 6 cylinder, WOW :o Link to comment Share on other sites More sharing options...
dcairns Posted October 16, 2002 Report Share Posted October 16, 2002 andythompson005- As I have contended on other theads here, I think the Whipple will bring the SS up to par with a stock Lightning (not everyone thinks so, but we will see ;) ). Whipple says it is getting 470 HP and 532 lbs/ft torque out of the Escalade, which has the same motor. But a Lightning killer? Nah, those guys have had too many years to tinker with their trucks. They are way ahead on available aftermarket mods. And after a point it becomes a matter of "how much money and engine life do you want to spend", at the expense of everyday driveability. The SS with a Whipple will make a fast and fun truck for everyday driving, and make a respectable showing at the drag strip, which is what I am after. -Dave Link to comment Share on other sites More sharing options...
variant Posted October 16, 2002 Report Share Posted October 16, 2002 is this the first chevy with the " SS " badge based on a small block? and no big block motor? the Impalas & Monte Carlos were big blocks were they not? and of course the 454 SS trucks... I still have dreams of a 68 RSSS camaro.... and a mullet.. J/k Link to comment Share on other sites More sharing options...
