Oscar,

With just over a week to go I suggest you dial in the important stuff.  Brakes, running temp, AC.  The fuel gage can be tweaked when you have a couple of days to pull the sender and make the necessary adjustments to get it as close as it will get...probably never right on. 
As for the AC, what unit are you using and did the kit provide a Wide-Open-Throttle switch that kicks off the compress under full throttle operation.  If that isn't adjusted right it could be tripping the compressor too soon.

Well the gas tank sending unit is a 20 gal. Not 16 so, that's why I'm thinking the float must have a pin hole in it.  I don't recall if it was plastic or bronze??

The A/C is the original underdash but it was upgraded to 134 and Sanden compressor some years back by the previous owner.  I'm not even sure if it has a WOT cut off switch.  Eng. Temp seemed ok, it didn't get past the "E".  If I get into traffic or held at a light too long, it will start creeping up close to the "M".  I usually cut the A/C off when that happens.

Hopefully the weather will be mild for those who don't have good running A/C's.

Well today I finally got the new 5.0, borgeson p/s and A/C all put to the test. I drove from Houston to Austin and back. Car did good. Started making rattle noise under the dash, something is loose.
No A/C used in the morming, it was nice and cool outside. Return trip A/C on the entire road trip,felt ok but seems to get little warmer under load. I noticed went I would let off the air would get little cooler? Not sure what that is.
Biggest surprise is one of the exhaust hanger bolts vibrated off, so I used a coat hanger temporary for the ride back. Other annoying issue was Gas gauge. I filled up in Katy and by the time I got to Austin it was at 1/2 of the last quarter tank! I changed the tank to a 20gal. For the Bash. So, by my estimates, It had sucked up about 17-18 gals!!
Went to fill up and only 8 gal. Of gas went in. So, something is off w/ sending unit. It was new but, float must have hole.
By time I got back to Houston, the gauge read empty, probably from A/C use?

So according to 8 gals at refill, I was doing 18.75 mpg on the way up there. Not too bad.

​I have the same problem.  20 gal tank w/20 gal sender.  At 1/4 tank indicated, I put in around 9 gallons!  I've had 3 senders with the same problem.  It acts like a 16 gal sender like I used to have.    Can't figure it out.  Fortunately I have not had to take a long trip recently.  But, if I do, I will probably take a 5 gal can along.  There can be long stretches between gas stations.

If anyone is interested I will email a PDF of my Gas Gauge Gage if you PM you email addy.  This is a set of templates and instructions that will help you adjust/bend/calibrate you fuel sender so that it will indicate E when you have 2 or 3 gallons in the tank.  If won't help the linearity of the sender/gauge setup but it will let you know when it's time to add fuel. 
Setting this up takes a little time so you don't want to dive into it if you don't have a few hours.  Also, you need to  remove the sender so the tank needs to be nearly MT.

I set our's up to have about 4 gallons (22 gal tank) when the gauge is at E.  At 1/8 indicated it takes 16-17 gallons.
