Looks like another one has been converted. Gotta love the enthusiasm of a new recruit!
Cool info though in all seriousness.
I wonder what the difference in tolerances is/was between parts manufactured now and way back when. Obviously things are WAY more precise and finite now than they ever could have been 45 years ago.

"Bounce off that ounce and soon a pound will find itself homeless"
I love it.
It's fever season and I need no cure. LOL
Plus, do you guys know what that GTX weighs almost all steel? I'll let the owner tell y'all and quick too. You'll be mighty surprised. He's been at it incognito for a minute.

I started my weight loss log back in 1997 when I started a full points season at US41 DRAGSTRIP in Morroco, Indiana. At that time the GTX weighed 3380 lbs. My last entry was for swapping out the hood pins to aluminum. The GTX is now down to 2904 lbs. With the recent items as posted earlier it should be under 2900 by Christmas!
The GTX body is all original including the factory paint except the hood. It also retains all it's original glass and trim!
Attached is a picture from one our NHRA INDY ET FINALS appearances.
I have owned the GTX since early 1970 and started racing it at the old US 30 DRAGSTRIP near GARY, Indiana. The GTX only had 8,000 miles on it when it was stolen and recovered then bought by me and turned into a race car!
I'm interested in this build. I'm assuming at 2900 it Has an aluminum block, alloy 9" Ford and a glide? Or maybe not and there are far more tricks we need to know about. Backhalf? What does it run, combo? Thanks Doug

Cat's out of the bag. Perhaps an aluminum floor?

This is going to be more fun than I thought!
Doug,
The all time best which turned out to be on a warm day is 9.499 at 139.60MPH!
I am running a non numbers .030 over 1970 iron block!
I started out with this car almost 47 years ago. The only things I've had longer are my birth certificate and high school diploma!
You have to know what the car likes. Not long ago my chassis man built me a set of merge collectors no charge just to see what happened? I made a test run for a baseline cooled the car off and put on the merge collectors. I made a run with the new collectors and the car slowed down a 10th !@#$%^&*()_! I made another run when it was cooler and no better. Took them off and gave them back!
Have done a lot of research since and maybe other things should have been done to make them work?
Weight off the front half is a given but don't expect a 10lb loss to show up on the next time slip! Other things like air density and track conditions could wipe out the gain on that day.
So I will open the door for a sneak peek!
Take a look at those back tires in the pictures. They are grabbing the track and wrinkling up. Those are the lightest wheels I could afford at the time. There are no tubes inside them and no screws in them. I did my home work and don't like drilling holes in new expensive wheels.
You want to go in deep?
What did the screws save besides rotating weight?
Less aero drag running around in clean air by the back wheels.
I am doing my home work to see if I should put back the front turn signal lenses to keep the air going into the two big holes in the bumper??? I thought removing the front turn signals would benefit two fold. One being less weight and another being more air to the radiator. But if you have so much air building up in the engine compartment that you have to add a center hood pin to keep the hood down maybe there's too much air?

Mopar John This front bumper made an ET difference. 7.5 lbs verses 60+ lbs with the stock bumper + liner. The front wheels are factory Chrysler aluminum wheels ( 15X6 ) without all the fringe. They weigh 13 lb each. Point is, you don't always have to spend big $ to go lighter.

Yo, I'm sure you have the Monogram model car version of your car in the same color and all right? I got it covered! In my collection of model car kits I have one original issue green 1970 GTX kit by Monogram unbuilt and still in the wrapper!

What does it run, combo? Thanks Doug Doug, Your guess of a alloy 9" Ford rear end is a good idea but wrong. I can tell you that it's not a Chrysler 8 3/4! When the GTX got into the 10 second area and running a transbrake I started to have ring gear failures! As the GTX got quicker they happened more often and there were more teeth missing! Then it started to destroy the pinion gear also. I have attached a picture of the failed gears. They get worse left to right. The one all the way to the right has the most damage and was the most expensive! That was one to be a high quality gear and I had it lightened for LESS ROTATING WEIGHT! I'll bet I have $7-800.00 in that ring and pinion! OUCH! I have a close up of the lightened ring gear in the second picture. I don't have any sponsors just me and the wife. So you can imagine after spending thousands of dollars on a new 493 stroker ( I let that one out! ) with my wife along side the wall for the first hard pass and the GTX moves about an inch !@#$%^&*()! Then I have to tell her that were going to have to go buy a new rear end that will hold up with the new motor! That was a hard sell!
