I'd still have to shake the car down, and bolt check everything before my first trip like that, so...it's just cutting it a little too close.
I will make one of those for sure. Looking forward to meeting you, and checking out your car also!

Totally understand. You've waited this long so there's no sense in rushing to make a monthly gathering.

I need to get my high speed vibration figured out so I can be ready to head towards you and the mountains once the weather warms up.

I hope to get the TA up there eventually. Would like to just check it out in general. Should I just look for a track day or any given weekend?

Trey, the track is open to the public, and admission is free. Come springtime, every weekend will be a very busy time there. I've been in there Saturdays, and Sundays, and both days were filled with busy garages, lots of race cars both late model, and muscle cars, as well as exotics. Perhaps check their Facebook page, or website, for a particular event. Only downside I'm aware of about the 2 mile track is that it's a counterclockwise design, instead of the usual clockwise road course design. Who cares, right!?!?

Sounds like I'll be heading that way one weekend for sure then!

Update...
I've logged 91.5 miles on the car. It rides great, runs strong, although I haven't really got on it yet, and turns heads. Never goes over 195 degrees, and stays at 180ish while driving. My radio has a really annoying high pitched whine, while running. The Flowmaster mufflers are painfully droney, and actually a little too loud for what I want this car to be, so they are off, and I installed some Borla ProXS units. In all the sound clips I listened to, they sounded great.
Here's what I'm dealing with currently. The 12 bolt that I bought came with a posi unit. The unit looked clean, and had been rebuilt, so I installed it. The rear end was buttoned up, but while moving the car around in the shop, I noticed that it chattered, even when pushing it. I figured it must have been dry for a while before I got it, and it would loosen up after a first drive. Ok, that was rear end build number one.
As the build came towards the end, I purchased some Moser axles, a new cover gasket, and lube, limited slip additive, etc. That was rear end cover back on number two.
On first drive the rear end was scarey loud. I mean, I'm not gonna make it home, loud. After some research, I realized that I should have clearanced the axle ends at the c-clips. My pin went in, but it was tight...turns out it was too tight. The axles needed more clearance than I had, so I pulled them out, cut the needed material, and after several ins and outs to find the necessary measurement with my feeler gauges, I once again put the cover back on with a new gasket and lube. I was sure that my clutches were noisy, due to my c-clips offering too much preload on them. That was rear end cover back on number three.
I go for a drive, and it's quiet. Yay! Wait a minute...after twenty minutes it gets noisy again. Now I'm aggravated. Back in the shop, and I pull the posi out, and inspect the clutches. They look ok. Light wear in the center of the disk, but not bad at all. What gives? So I talk to a friend of mine who does rears for a living. He gives me some advice, and put it back together. I go to run a tap on my ring gear holes to get the hardened red loctite out, and guess what happens? Yep...broke a tap off in the ring gear. Yay...so, I drive down to Summit, and buy a new ring and pinion, lube, LS additive, gasket, etc...put it back together for the fourth time.
My rear end guys advice was to simply drive it. Find a parking lot and do circles and figure 8's left and right. These units need a break in, So last Saturday I went down to a big parking lot, and did just that. I spent 20 minutes solid going in tight circles, and eights, both forward and backwards. No cars around at all, so I loosened it up as much as I could. Left out of there, and so far so good....Almost home and it's noisy as before. I'm over this by now!
Pull it in the shop, totally gut the rear again, and I order a new Detroit TrueTrac. I go to install it this past Thursday, and I realize I've made a mistake. The posi unit was a 4 series. It had a 4.10 gear on it when I got it, so I put a 4 series 3.73 on it...no problem. Weeeeeellllllllll.......I ordered a 3 series Truetrac, in my hurry to just finally get this rear end disaster behind me. So, I've got another 3.73 on order...in a 3 series.... I am not putting a ring gear spacer in my car....And lube, and gasket, etc. This will be rear end cover back on number 5!!!! On the plus side, I can set up a ring and pinion with my eyes closed now! That's hot rodding!!
More later!

Yes sir. Trey, you have to check out AMP while your up here. Free admission, and no kidding, it's a world class facility. Bring a camera!
I will touch base with you, concerning C&O.
