I have held all along that it will get an upgraded 400 HPish 6.0L..and if there is a supercharger, it will be a factory installed options.

Another Site and Guion have said that we will be seeing a Supercharged SS from the factory instead.

Now the site the originally reported that the truck will be supercharged is saying the the truck will come in a regular cab version with a six speed and a 385 HP version.

SilveradoSS.com claims the 05 is done and will see no major upgrades...plus I am hearing 05's are already coming off the line.

I am cunfused as hell on this one...as there seems to be a lot of conjecture.

My opinion on the Supercharger is why bother? I am sure GM has a regular engine that can make enough power...plus it would be easier to certify.

Also of note...

circa 2006-07 The Trailblazer SS is coming out with a 380 ish HP engine and six-speed, plus there are rumors the SSR will get a very similar drivetrain soon.

Is it reasonable to think that GM will offer the same 385 HP engine and six-speed in the Silverado SS, Trailblazer SS, and SSR (maybe more power here?) with a phase in beginning in 06. Then maybe they are going to offer the supercharger through the dealers for people who wanna chase Lightnings?

I know the supercharger is already engineered...it's just a matter of whether they will offer it through dealers or as a factory item?

Also, by offering an upgrade through a dealer...does the upgrade have to face the same emmisions standards?


Just trying the put the puzzle togethor

 

385hp from a SCed 6.0. Why even bother except....

I guess they're not bothering to lower the compression and change out the cast pistons for forged ones.

It is definitely not easier to certify a new hi-po NA 6.0 than an unchanged production 6.0 with a blower strapped on. The idle and part throttle characteristics of the blown V8 are virtually unchanged from the NA one. Whereas changes in cam require re-engineering the ECU on all levels of operation and therefore more costly recertification.

This looks like a quick and clean factory or dealer installed option that costs GM almost nothing in development but can easily bring $3K-$5K per vehicle profits.

Not going to be a threat to Lightnings or SRTs but it's a nice feature.

 

That would be the case out here in California.

 

GM's got alot of grief on the current Silverado SS, and not just from us either.... perhaps grief is too soft a word for it.

I can assure you that the next one is going to be blown, I got that from about as good a source as you can get.

As for the other stuff, I have to revert to deductive reasoning (otherwise known as glorified guessing).

I'd say that the a version of Silverado SS becoming a RWD, regular cab, shortbed is probabally a reasonable assumption.

GM could very well continue with the current AWD extended cab one along side... Colbalt, Impala, and Monte Carlo all have regular AND supercharged engines, so why not 2 Silverado SSs?

 

I was going to ask that . Is it possible GM will have a 385HP SS and 450?hp+ Superchaged SS? Like you said the Monte and Cobalt each have a SS and S/C SS.

If the 385HP reg cab SS comes in at $30K that might be my Camaro replacement (until '07-'08 )

 

The regular cab Silverado SS...is not meant as a replacement for the AWD extended cab Silverado SS.

 

random thought...

If GM used the 454 in their SS truck 10 years ago, whats stopping them from using it now?

 

I agree!

496SS does have a nice ring to it.

Here's how I'd do it to get around any CAFE problems...
regular cab, sportside bed with one of the Marine versions of the 496 backed by the ZF 6 speed with a revised short-throw shifter in a 3/4 ton chassis. The suspension would be like the stock 3/4 ton, but lower. 17x9" wheels over the 3/4 ton's larger diameter rear brakes on all 4 corners. Good luck breaking anything in that drivetrain with anything less than a 300 shot

 

I'm not a truck guy, but that sounds really intriguing.

Especially in light of 500 cubic inch, Viper powered Rams!

 

That's a great idea! Kinda like a modern version of Dodge's Lil' Red Express, which was built in a similar manner to get around emissions.

But then we've have some whiny-*** complaining about "stiff ride" or some crap like that

The major problem here would be the use of the Allison. It requires the 2" body lift that's currently standard on the HD pickups. If one wanted to maintain the half-ton ride height, it'd be necessary to stick the 4L85E behind the 8.1 L, and live with the "torque limiting" that's currently implemented in the Avalanche 2500. But at least that'd be the crap out of having a 4L60E.

 

Eric, I didn't say a thing about putting an auto in there

I do wonder if the ZF 6 speed that's available for the heavy duty trucks is as big as the Allison.

 

You know, using a gen III/IV smallblock for a Silverado SS makes so much sense. From the point of view of packaging, cost, fuel consumption, emissions...and yes, probably even power production.

But oh man, AdioSS....I think that you've hit a chord with me here. A truck is the only place a performance variant of a big block could ever realistically occur again. I have to admit, it'd be so cool!

No wimpy blowers. No odd sounding V10's. Just nearly 500 cubes of good ole' fashioned Chevy big block torque!

It would handle like a pig.....but who cares...it's a truck.

 

Not sure about the ZF, but the NVG5600 that's used in the HD Rams is absolutely monsterous. It's also 360 lbs, due to the cast-iron case. I can't imagine that the ZF is small or light by any stretch of the definitions.

 

you don't need to add a Supercharger to get to 385hp.........

 

Ford does
