C bodys are cool though. A 65 300 2dr. base weight is 4100 lbs. You could get one down to 3700 to 3800 easy. I drove a 65 New Yorker 2dr. ht. that was red with buckets and a console with a 413 for years. A real head turner. If you want to talk heavy my 68 Imp. LeBaron 4dr. with dual air and power everything even wing windows and a heavy Auto Pilot. Base weight 4840 but mine was 5000+. A C Body is not even close to a Imp.

My 68 Fury H/T lists at 3680 lbs with a 383 - 160 more than a 68 GTX with a 440, so one of the "least bulky" C's, BUT it has A/C and a 9 on the build sheet for underbody protection, its pretty thick down there - saw someone say they got 90 lbs off their challenger by removing the all the goop from underneath, scary.
My aim is for 12's (high 11's?) and still be able to drive the 125 miles to my nearest drag strip with a 383 stroked to 450 @500hp comfortably
Have ally intake, radiator, water pump n housing, ally heads are my next purchase.
Ideas swimming in my head:
Loose as much of the front as possible and leave the back end alone until scaled, the ass-end is easy to lose weight from
Split bench in currently, will pull and weigh and evaluate, most likely to be replaced with some Japanese oem seats of some description (safer than cheap sports seats)
LiPo battery in the pass side of firewall, shorter runs for heavy cables
Re-wire with decent new txl wire and get the voltages required down everywhere I can
Replacing all the A/C with lighter options - sanden compressor mounted below alt on pass side and more ally pipe vs rubber hose, same with the heater hoses. Its a huge temp variance where I live, 37 to 115f, need a heater for local regs and A/C cause it gets bloody hot
Replacing as many engine bay brackets with ally as possible
Drilling Vee pulleys in the space at the the bottom of the V and lots of holes wherever I can (evenly for balance)
Cutting the exhaust crossover and coil mounts out of the performer intake and a few strategic holes elsewhere
Steering Rack from one of our local fords, havent done proper measurements but its not too different in width to a mustang rack, which isnt too far off whats needed for a C and way lighter than the box/drag link set up
Front Brakes, have the 2 1/2x11 drums, have the 69-71 11.75x1.25 disk brake set up, its heavier than the drum set up.... will be adapting to 11.75x1.1 disks from the same local ford above initially (cant get the original rotors here) and lighter calipers later
Wheels, tricky here, there are not alot of actual lightweight rims floating around in correct pcd and offset used here, holding out for something that looks good but isnt heavy, 15's or 17's x 8-10, whatever comes up for good value, currently only have 14's so need to go up for the disk setup
Radiator support, bumper brackets & headlight buckets re-done in ally
The inner fenders bolt off, but are structural until some frame connectors get added, then I will look at ally or fiberglass or carbon fiber, steel are 12 lbs ea
Here we are not allowed to use external fiberglass front panels on the street unless its certified by a manufacturer/certified specialist - completely custom and going to be out of my budget for some time, pretty sure my sheetmetal skills arnt as good as FMJ's and I doubt I would be happy with any ally hood, guard or bumper I could produce
If the Windscreen (windshield for you guys) ever breaks, the dash will come out and be done with F/G or C/F , before that will crawl under and have a look at what steel can be replaced with ally, prob at same time as AC
The door vent glass has a winder mechanism, that can become fixed and lexan, small cranks moved to the regular window winders
I can live with the back widows becoming fixed and possibly lexan, I have AC and rear passengers be dammed
Plus lots of the little things mentioned on this thread, drilled bolts and suchlike
Oh and I could lose 30 lbs too lols

Geeze, I didn't know that they could be that much heavy difference between the Dodges/Plys to the Chryslers. Some cats here in Brooklyn had some extremely stout 68'-70' Buick Deuce and a quarter's that were giving mid size and small size cars the break. One particular Cadi convertible was totally gutted running its original 500 cubic inch mill on lots of mojo juice. Thing would lift the wheels at launch.
C-bodies, they carry the worlds weight. Well... you could get a pretty stripped out Fury/Polara... whereas every Chrysler, save the VERY odd Newport, got the full treatment. You're looking at a 2-400lb minimum. Also different suspension components, maybe slightly longer (?) and just... MOAR car. The Imperials? Dont get me started. They're WELL bigger/heavier. Also dont compare to anything 455 Buick. As the saying goes... "Buick math is different". With the torque those engines make (from the factory... not after a few key (not so easy) mods like our 440's need)... they're fast off the lot. The Buick guys have been making sleepers out ov their full-sizes for decades... and that is a game they love. I've seen full-weight (5000lbs) 11 second 70 Electras. MANY full-load GS's (4000lbs+) in that range. 10 second cars on a little nitrous. These were NOT dedicated race cars! Its this profane little amusement they have... those full-size sleepers. I used to run 455 Buicks... they got a lot right that Mopar's didn't. They just topped out at a certain level (like the above), and going beyond that got VERY expensive... unlike a 440... which can run into the 10's, even 9's cheaply. Cadillac... on the other hand... is the best ov all worlds. Its still the best kept secret in the big block world. Like the 440's... you recognize and address a couple key weaknesses, and you've got some SERIOUS power to play with. For the cost ov some tricky machining (about a grand), guys have made 542, even 572cid junkyard engines. Cadillac sh!te can get scary...

This car was for sale here a few years ago... PERFECT for a sleeper. First year ov the chassis (lightest), stick, 6-cyl car (so EVERYTHING would be minimalist), no options, and a Fury I... base model. Really wish i'd bought it. The black one... well... this was where i was going with my 71 Fury III (NOT the best model to start with), before i sold it.
If we still had a street-racing scene here... i tell ya...

Weighed mine at the track since some recent weight reduction. Did the front weight, whole car, and then rear. Not exact, but close enough to get us in the ball park
3365# Total W/ Driver 1790 Front 53% 1580 Rear 47%
Gonna work on taking some weight off the nose to even out the distribution and bring overall weight down to 3300. Fiberglass hood is step one that should net about 40 pound reduction.

I see Lexan windows and a fiberglass dash in your future... My 'glass hood arrived last week from AAR/Stinger. Have to say it seems lighter than I expected. Didn't weigh it yet but it can't be more than 25-30 lbs if that. I will compare the steel and 'glass when I take the steel one off. If I remember, OE A body hoods and hinges are like 62 lbs? Probably in this thread somewhere. Got a increased height dual snorkel scoop for it, still debating whether I want to put it on or not. Doesn't weigh a whole lot, maybe a few pounds. The aluminum hood pins I got weigh next to nothing but I'm thinkin' they might need some fairly beefy mounting brackets to keep it solid.

I finally made some progress on my new exhaust.
pulled the old system down, 3" TTI H-pipe system, 2 chamber flows, modified tailpipes to go around the fuel cell all the way to the bumper, weighed in at ~60lbs total, lighter than I anticipated.
I have one of the aluminum mufflers buttoned up, modeled after the now defunct Vibrant aluminum bullets, 3.5" ID, ~5" OD, 14" long case, rolled the perf tubing for the center, and roller the outer case, integrated a 45 degree dump into the outlet. The perf tube is wrapped with fiberglass cloth, then the case was packed with fireproof mineral wool meant for 3" pipe.
Finished welding up the first one today, and threw it on the scale, 4 lb 4 oz. These will be connected to Stainless collector extensions via an aluminum x-pipe. Buttoned up the new exhaust today. Stainless collector extensions to an aluminum x-pipe and home-grown aluminum mufflers. 3.5" dumping before the axle. I could have found some thinner stainless for the collector extensions, but I already had the 0.065" wall stuff. Took a test drive today...just as a realtor was showing off the neighbor's place...haha. It is quite a bit louder, but has a good sound. Car feels a bit more responsive. Wednesday is supposed to be a T&T session if the weather holds out Since this is the Jenny Craig thread... Old 3" TTI system was 60 lb New system, clamps and all is 24 lb Saved a bit of weight, and hopefully got rid of some of the backpressure, plus it kept me out or trouble for a couple weeks.

New system, clamps and all is 24 lb I might need to look into the stainless exhaust deal, that's a nice weight savings. My exhaust is REALLY heavy!

On the lighter exhaust you can move the center of gravity of the car up. That can be good or bad. For a drag car I would go lighter but if you want to the car to handle maybe. If you lower the car a lot you can move the center of gravity to below ground level and that is bad so lighter exhaust is better. But if the car wasn't lowered to scrap the ground you could be raising the center of gravity higher in the car and it will not handle as well. This just means you need to look at the hole package. This is food for thought.

The aluminum tube is 0.065" wall as well, fairly thin for aluminum.
I went from a full 3" system to the bumper with Flowmaster 2 chambers to 3.5" "glass packs" that dump before the axle. I wasn't expecting quieter, but this thing sounds like I'm on the infield during a nascar race when its "on the pipe"
In terms of messing up the balance...I removed 1% of the total weight. I have /6 torsion bars an no sway bars. I am not burning any corners. Besides, for a race car, you should probably make it as light as possible, then add ballast where you need it as necessary.
On a related weight-loss note, I had to get a tooth pulled last week. I am down 10 lbs likely due to not being able to eat too many solid foods, I doubt the tooth was that heavy...
