That Elephant has been a test bed for all parts factory to see if they can withstand the grunt. I've never heard of a broken throttle lever assembly.
You are truly a doozy Hemi-itis.

A compilation of heavy parts.
Winters coming, who knows what civility has been transforming in the shadows.

What can weigh this much and be narrowed down to.......

this......?

I have an idea but I won't tell. My bet is the 40lb part was already way lighter than a stock part?

DVW's crystal ball is correct.

Well, Winter wonderland season is almost here and I never got out this season at all.
So in the meantime while taking 5, I figured into what lurks under ones dash or through out the car without knowledge.
Here's a sample of what could be un-had by simply studying what is not needed anymore or what is just simply too long and in need of shortening.
Copper is heavy along with its skin cover. Snip and trim away guys.

and getting rid of the "rats nest" also makes it look good with the added benefit of future electrical maintenance a breeze. i just hate a ratty wiring mess. i'm in the midst of re-doing one such mess at the present time. just on the front lighting circuit at the radiator support, i eliminated five wires and 18 [], yes, 18 splices ! what a mess ! of those splices, all were made using junk, cheepo terminals that were crimped wrong, and all but three crimps pulled apart by hand with no effort. this was a NEW universal harness install, installed by a guy that has absolutely no idea how to do this, and shouldn't be allowed around electrics in any way, shape, or form. i have completed the rear lighting circuit, and it was almost as bad. the underhood harness is done except finalizing the starter relay circuit, and the under dash mess is next. the wires there were just balled up and stuffed up into position anywhere they could be stuffed. the steering column connectors are spliced with at least two or three butt connectors over an approximately six inch span. i will have to try to remember to get a couple of pics of that mess before i repair it. did i mention i hate hack wiring ?

Agreed.
Rats nest. It's the equivalent to dirty dishes left in the sink for days with food rusting on them.
I don't have the time right now, but sometime after this Xmas, a lot of wires under my dash and throughout the carcass are getting the X.
Never mind Brexit, this will be Wixit and probably a pound or two or more getting the boot.

Been there done that.

I am sure this has already been covered, but the XP Flex copper clad aluminum cable is nice stuff. Not too pricey either if you shop around.

I got mine from:

I forgot to mention since this thread at times consists of the cost of things and or services in that snipping, crimping and removal of access wire/s is next to nothing in cost. Maybe a few good connectors and heat shrinks is all that is needed.

For those that have early B-cars and wondering what the rear bumper weighs, here go's.
64'-65' Dodge rear bumper weighs in at 22 lbs stock. Good weight all across the rear end of the car.
64'-65'Plymouths may be different.
This pup is a new one and the next time ya'll will see it, it will be black chromed and mounted on the car.

I'd expect it to be going for a Detroit Bath....

Nah, I thought about being that I'll be in town with it, but it is the leading rear edge of my car and I would want it to be strong in case of a rear end hit. But also it would keep that even steven weight across the rear end facade.
The black chrome affect will look sinister with the black exterior.
Black chrome is a black art in itself and looks eerily fantastic if done correctly.
For those that have never seen Black chrome, below is an example of a wheel with black chrome affect.
Not my wheels, by any stretch.
Mine are pure black like the heart of the car itself. LOL.

I'm on your doorsteps Fullmetal- weighed my '65 Belvedere I post this weekend. She came in at 3290 empty. I'm thinking next will be some Proglass for the windshield and aluminum bumper brackets (by Moparts member Jeff).

My car is a street/ strip set-up like a Super stocker; low deck wedge, 727, Dana 60. Had it out for a test/ tune this past weekend practicing 1/8 mile & starts. Managed a 7.10 1/8 & some 1.50's on the new 9" slicks.

I thought I heard a knock at my door recently. LOL.

Yeah, a molded Pro-glass windshield will save you a small respectable amount up high and front of the center of gravity belt. IIRC it was somewhere in the 11 Lb range that was eliminated. Still crystal clear to this day with the occasional TLC practice.

I got mine from Kramer, a little pricey but it was an aerodynamic bubble type like the 64' 2 % AFX'rs. See below compared to the true AFXer in the next lane.
Bumper brackets will save you a nice amount down low and very front of the belt.
Later this Winter, I am installing what is probably the first aluminum chassis bracket mounting bosses of their kind. This is the solid mounts that protrude out of the front longitudes of the chassis and the bumper brackets bolt on to. After it is bolted on and smeared with a little body putty, it will look stock and hidden. 2 Lbs total will be eliminated.

65' Bel 1's are already lighter than the Dodges by just a few pounds and a very good platform to start with.
That 3290 is lean.
1.50's are pretty darn respectable.
I'm not sure what you have done to it so far to get here, but I'm sure that there is a lot more there.
I love Street/strip SS cars.

Here's a pic from last Saturday. So far, basically fiberglass hood, chromoly K-member, basic alum. engine components, no back seat, glass bumpers, Strange discs on all fours, alloy wheels, Braille battery (up front).

Still want to remove the heater plenum as well as the other parts previously mentioned. Then, it's getting picky- like you are- with a couple pounds here and there. I might gut the door mechanisms except for driver's door. If I find the money tree, I might do a chromoly roll cage instead of the mild steel one that is currently in it.

The end goal is 3200# and tuning the engine combo to run 10.00 Currently, I think it will do a 10.50 as is.The 470 made 655 HP/ 633 FtLb. on the dyno.

Dang, never mind the power, that's some torque.
Car looks nostalgically sharp with a nice rake.
You should be able to reach 3200 easily in your sleep. After that, the bug may bite you to go to no-mans land like I did and find all the hidden ounces.
I would suggest to gut the doors sparingly and leave the windows, locks and opening mechanisms to function like stock. You would be surprised on how much can be gutted and still function like stock.
I'm about to install my year one A-990 door panels soon, so I'll photograph the internals and inner skin to show how it can be done.
Suggest chrom-moly roll bar or cage. About a 30-50 lbs savings depending on how many points it ends up being.

Have you removed all of the undercoating/ sound dead material?

Love the "Color me Gone" theme paint.

UMMMMMMM
