I will have the car scaled. There is a great shop in Nashville that sets up circle track cars. He has a flat plate and scales. The plan is to get the corner weights perfect so the car handles as well as it can.

My x-pipe came in today, but I won't be able to get it welded up until Thursday. Aside from that and the shaker the car is buttoned up and ready for a long drive.

Tomorrow I will post pictures of how I ended up putting in the rear end travel limiters. These will keep the rear end from dropping too far down and the springs from dislodging from the upper pockets.

Great progress Andrew, Let me know when if your coming down to Nashville with the car. I want a ride.

Brian,

I will be down in the next couple of week to get the corner weights set.

Today I got the exhaust buttoned up. A new Dr.Gas x-pipe was installed and connected the headers to the mufflers. The car is very quiet. Almost too quiet. I has a nice deep tone. It is a hair louder than a new ZO6 Corvette. I got the wideband hooked up as well and as suspected the car was a little rich. Once I drove it a little the ECU started trimming the A/F ratio and now it is very close. I may not have to get it tuned at all. We'll see how the WOT A/F ratio is on the dyno.

I also weighed the car on the new scales at Beech Bend. I had 1/3 of a tank of gas, no hood, no passenger seat, and I was in the car. I think I am about 275.

Anyone care to guess what the car weighed?

Cool,

Give me a ring a day or so before you head down so we can meet up. I may even have the body back on the vette by then and you can take a little memory rod with the LS6.

I searched this thread but did not find any specifics on the rest of your exhaust besides the x-pipe.

There seem to be a bunch of questions in the exhaust section about quiet exhaust systems, and you seem to have figured it out. What kind of mufflers and headers are you running?

The headers are from Edelbrock. They ar ethe new LSx swap headers for 68-72 A-bodies. They have a 3" collector that goes to a dr.gas 3" X-pipe. The mufflers are from a company that I do not believe is in business anymore. It was called Straightline Performance. They are very big, similar to Dynomax Ultra Flows. From the mufflers I have 3" tailpipes. So the system is 3" all the way from the collectors to the exhust tips.

Andrew, did you ever check the bump steer on the new ATS spindles like you did the B-body stuff. I have pretty much the same setup you had, and I am thinking of doing pretty much the same conversion. Just wondering what the final results were.
