That is interesting. I take it you are replacing the front sway bar with the one shown in the picture. Looking into replacing my front swaybar. I was thinking a 1.25" tubular unit.

No, it is a rear anti-roll bar. Here is an install pick (not my car)



It is to cure the twist: (my car)

I got faked out by the mounts to the axle. I thought they were the frame mounts for the front. My 1" rear sway bar does not mount to the axle. I may have to change that. You are getting a lot of air under the left front tire.

Yeah, I have a 1" sway bar that bolts to the lower control arms now. It does fine until the nitrous is involved.

1989GTA

Hmmmm, maybe mine will be alright. I will just have to wait and see what it does at the track.

I boxed the converter up and sent it back to Circle D for a restall today. Pulling transmissions sux.

1989GTA

What was the old stall and what will the new stall be?

The old stall is a Cirlce D 245 MM 2B. It would flash to about 2800 or so on the motor. I told Chris to give me as much converter as he could that would still take a 200 shot of nitrous. We will see what he comes up with.

Here is a chart of Moog's front coil springs that may be handy from other guys doing A-Body LS swaps.

1989GTA

Thanks for posting the chart. I am running the 6 cylinder spring that came with the car MOOG-6204. Seems to be doing just fine with my setup.

You know, I was really considering the 6204 units initially myself. I was afraid the 5230 units would sit too low, but they are perfect.

Yesterday I also ordered some Viking Performance double adjustable front shocks. I am anxious to try those out.

Did you get your stall back yet?

speedtigger

iTrader: (16)

Oh yeah. It is in the car and running. It feels strong.

1989GTA

I was just thinking that as seeing I have the two door post model it might help some with the body twist. Guess I will just have to wait and see.

1989GTA

What is the latest on your exhaust system? Is it still the same? I think you had 1 3/4" headers to a 3" collector. Then necked down to 2 1/2" dual exhaust. Is that correct?

Great thread, just read thru it, home sick today,

It went 2 tenths faster with the new converter. From 11.27 @ 120 to 11.07 @ 120. Knocking on 10s on the motor now.

The new converter definitely runs hard, but there is some sacrifice to drivability though. Especially in a car like mine that does not have a computer controlled lock up in the lower gears.

1 3/4 into 3" collecter. 3" duals with Pypes stainless X-pipe and T/A Performance 3" tailpipes with the extensions to the rear bumper. The extensions reduced the resonance inside the car notably.

Thanx Steve. I was sick yesterday and Sunday too. But, I did not feel like posting.

Here is a slow motion nitrous launch:

And, at full speed 10.25 pass:

"The extensions reduced the resonance inside the car notably." Thanks, I will do the same.

"Knocking on 10s on the motor now." That will be my goal as well.

What is your motor build specs?

1989GTA

L92 with TSP VVT3 camshaft. LS3 intake manifold and LS3 throttle body. 1 3/4" to 1 7/8" headers with a 3" merge collector. 3" Pypes x-pipe and TA 3" exhaust. Ported heads and throttle body. 6L80 transmission with a Yank SS3200 converter. 3.23 gears with Eaton positraction. The 6L80 has something like a 4.05:1 first gear.

Before I forget what extensions did you use?
