The new drag racing season is coming up quick and I decided to do a few things to help the car get quicker.


I did a Lexan project. I made a rear window and quarter windows out of 3/16" Lexan. I'm happy with how it turned out.








For the rear window, I used a 3/8" x 1/2" x 15' adhesive foam tape and #8 x 3/4" and 1" stainless steel screws. I used a countersink tool to recess the holes in the Lexan.


Next I made aluminum front bumper brackets (frame) and lost a few more pounds off of the weight of the car.


I was a little disappointed with the total amount of weight for the glass, but it is what it is. Rear glass weighed 16 lbs. and each quarter window weighed 3.5 lbs. The Lexan rear window weighed 7 lbs. and the sides weighed 1.5 lbs. each so I saved 13 lbs.


The factory front bumper brackets weighed a total of 6 lbs. and the new ones I made weighed in at 2 lbs. total.


So after all that, I got rid of 17 lbs. off of the car and my goal is 40 lbs.


We are also talking about a new motor build, a 600-625 HP, 410 motor.


We got a bunch of people telling use we're crazy and that the block won't hold up or the motor won't last but we also got some good names saying otherwise. Most important thing we need to do is sonic test the block first and it that is ok, we'll move forward. This will probably happen over the next two years. My wife promised me that after she graduates from nursing school and she has a job, she will buy me the AFR heads....WOOHOO!

 

Very nice - good work.
Less weight = more horsepower
-100 lbs = 0.1 second improvement
You are on the right track, I got my '68 down to 2800 lbs and still had a heater for those frosty mornings and cold days in November and a finished interior, abet, poly drvr seat only, and a working interior light for reading time slip at night.
Replace steel with alum - rad support, inner fenders, all brackets, fiberglass bumpers and alum brackets, and any item of steel. Fender fasteners and the like - non-safety items - had alum hardware.
Lighter tires/wheel combo, you know the drill.
Good luck

 

The car weighed in at #3000 w/o me and I want it to be #2900.


Just like you said, #100 is equal to 0.1 improvement or so they say.


With the aluminum heads, my goal of #2900 is easily in sight.

 

I had cast iron Crane Fireball heads.
You'll get there.

 

and you were at #2800 WOW!

 

I have no inner fenders, fiberglass front and rear bumper, fiberglass cowl hood and deck lid, 1 poly seat, plastic dash cap, 5 gallon cell, aluminum radiator, just about everything you had. Now my cage is a 14 point cage, 1-5/8" mild steel, the rear frame is a 24" pre-welded for ladder bars. I'm using Strange coil overs, tubs are 40" aluminum, no head liner, carpet and I removed the backing, custom wiring.
People tell me that #3000 is good, but I need more off of it.

 

Yes, mine was OE unibody, OE gas tank, 6-pt roll bar, OE suspension, fiberglass hood, steel doors, full interior minus seats, but had $3 sq yard carpet from rear window forward to firewall, OE glass w/regs, alum brake drums, and no radio.
You'll get there. Since OE tank, always ran a 1/2 tank of fuel.
