Here are two cool links for all the baby boomers out there:
The old 409's were fast for their day (early '60s) but were also very heavy and had two four barrel carburetors that had to be kept carefully tuned. Today's Impala SS has electronic fuel injection that's much more efficient. The result is a faster car (0-60 less than 6 seconds) delivered from a small block V8 engine, although purists won't acknowledge a FWD car as a being muscle car.

Just muscle in a different application. Torque steer is a challenge to overcome just as positraction inducing the rear-end drifting to the right was a challenge to correct for. However, there is something to be said for the torque flexing through the entire frame of the car and the sensations of having the front end lifting and the rear end dropping, full-throttle power shifting with or without the clutch, and the guttural lumpy rumble of a long-duration high-lift wild overlap cam trying to find an rpm to idle.

Hi clark & jpstax...
'Ya, I guess I'm considered one of those good 'ole rear wheel muscle car purists that you are refering to. But, you know, I'm not going to get all in a flap about this here and go on and on about this like some do...Wow, maybe there's finally some maturity here... Hey, although different, I feel that today's '06 /'07 SS Impala, and all that it intales, is one mighty-fine piece of performance machinery!!
Ohhhhhh Memmmmmmmories..!! Yes sir reeeeee bob... I can definately still remember sitting at those stop lights in my machine feeling that lumpy long duration / high lift solid lifter cam...Oh boy..!!
Thanks for taking me back....!!

As they say.. it could a million and one different things here.. It's very difficult sometimes to specifically know what the actual problem is mechanically just from a verbal explanation. If anything, I can try to give you some practical advice here... You say that "GM" doesn't know what the problem is ..well cuff, it's their job to FIND OUT and to FIX IT!!. Who do you call GM here... the Service Advisor , Service Manager, Dealership Owner, or the Regional/District Rep. over the Dealership ? How far up the chain have you gone ? Actually, You should have hit them in this order while firmly jumping up and down ... Let us know what you have done here. I don't want to seem like a smart ss here, but if you don't have a great relationship with this particular Dealership ,why not just go to another..
Good luck and keep us posted..

Sounds very much like my 06 problem around that speed. If I am gradually increasing speed, once it shifts to 4th there is an immediate noticeable drop in power and it takes a bit to get it back up.
If I have to maintain the 35-40 speed, according to the service advisor, the trans doesn't know which gear to be in so it causes a sensation of bouncing or vibration. Frank, Bryan or one of the guys suggested putting it into manual 3rd and it does help the situation although it is frustrating to have to do this since I've got 35 & 40 limits on a number of roads I have to travel.
Dealership says it runs as it should.

was back this morning..the tech at the gm dealer ship i'm at told me the problem lays with the timing going into retard mode when the car shifts into 3rd or 4th gear....and no it is not what it should do.that's why it has no power unless you gas it.it gives no codes or anything.........also tried bypassing the knock sensor,which gives full timing all the time,still didn't work for him...now they realy don't no whats wrong.......left it with them,,,,,getting pissed off....told them to check every which way it works...by that i mean...check the computer,tranny and what ever else makes it click........will let ya no what happens...
