Yep, totally stock. I might try disconnecting the front sway bars one night to see if that makes a difference to my times.

With those loose converters, how is the drivability on the street?
I had a loose converter in an older muscle car and while it made the car fast at the track, it was miserable on the street.
The same with a C5 I drove in. It made for a bad street cruising but worked on the track.
It's the old COMPROMISE. Like anything in life, you gain something but lose something at the same time.

New cars with converters are nothing like a non lock up car with a high stall. I personally really like the aggressive feel to the car, it's like it's always ready to pounce.

IMHO, most high-stall converters lose the low-end, street cruising capabilities. It is simple physics. The converter will spin or stall to a higher RPM before it engages to a 1:1 ratio with the transmission (not counting normal slip and without the converter lock-up clutch activating).
My buddy put in a 4000 stall converter and it feels bad cruising on the street. It loses the low and mid-range pull it once had. BUT, if he stalls it out, it will launch hard and fast.
As they say, it's all in the 60 foot. With a high-stall converter, the car launches hard but cruising around town stinks, IMHO. For a daily street car, I would never change the converter. If you race, then yes, it is the thing to do.
Converters can completely change the way the car drives. I would recommend driving in a car that had it changed out before one does it to their car. Either you will completely hate it or love it.

With the lock up converters the mileage on the highway is the same but fuel economy will suffer some in start and stop driving depending on how loose the converter.
Also the feel is almost feels like having a turbo when you start throttling up.
'06 Quicksilver Z06, you will have creep at idle but not as much as with the factory converter. A loose converter works real well with a big cam because it allows you to set you idle higher without excessive creep.

Yep, no matter what speed you are going when you go WOT it's ***** to the wall!

When I had my C5 I went with gears and torque converter. 3.42s and a 2600 stall.
Great for the street, very similar to stock driving, didn't have to give the car a lot of gas to get it moving, because it was not as high a stall rating as some, but it had a high STR, (stall torque ratio) which allowed it to hit very hard out of the hole.
But everything is a trade off. It didn't offer much from a roll because of the lower stall speed, and it had dead spots.
But for drag racing, I loved it because it gave me a very good advantage over the stock converter there and it didn't hurt my drivability too much.
Problem was, later on I decided that i might want to do a cam and heads package and discovered that with that 2600 stall, which was great with the stock cam, that I was looking at doing another torque converter too. And paying for that labor again.
That was part of what pushed me into getting my first C6.

I think you made a typo and meant "big cam". And yes, you are right about the cam. Thats why its important to choose a converter with a high enough stall if you think you want to do a cam.

Your history is a good reason to decide first how far, how fast, you want to take your car so you get the right converter the first time. I ended up with three converters in my 98 Camaro over a period of 8 years. Could have saved a lot of money had I done it right the first time. Ended up with a 3600 PI converter. That got the job done!

I have a Vig 3600 stall in my Z28 with the stock (3.23) rear axle and even it feels ok in around town/stop and go driving, I can't imagine how it would feel if I put some 3.73s in it.
