For those of you that have weighed your big block A-bodies, what were the front end weights of them?

Also, is there a rule of thumb for estimating the front unsprung weight for a stock disc brake set up?

It depends on how much aluminum parts are on your motor and if you installed it in a stock location, my old pump gas street Duster had 50.5 % on the front tires with the motor slid back one inch on the transmission mounts with elephant ears, the rear end was moved forward two inches also devil.
I've own a bunch of BB A body cars, stock BB 383 Darts and Baracuda are near 53 % on the front shruggy

Dang, My '68 A-Body convertible Barracuda weighs 3700 lbs without me in it. I was shocked at how heavy the car is.

68 Dart drag car. Backhalf with stock front. Fibreglass hood, trunk lid, and bumpers. Runs 5.70's 1/8 mile ets.

3035 total race weight. 1785 front and 1250.

Too front heavy IMO. Need to front half it over winter.

Our hemi super stock cars are around 54-57% front end wht. @ 3200# with dr. Actually we would put weight in front to help calm down wheelies. I don't think there is much weight savings in front halving.

I would be doing it for engine setback. It is 58-42 right now. Like to shift some weight to the rear.

It looks like the A body gains it weight advantage from the rear. My 64 Belvedere. Light bumper brackets (steel bumper), glass hood, aluminum -1 heads, Mega block, 2 carbs, light brakes, stock suspension, inner fenders, and fenders. 1810lbs on the nose w/driver (200). 54% @ 3350 lbs

You need to keep in mind hat the 108 wheel base cars are not exactly like the longer 110 W.B A body cars with the same motor on weight distribution :work;
My old pump gas Duster was right at 50.5% on the nose with me in it ready to race boogie I had moved the motor back right at 1.0 inch on the trans cross member and moved the rear end forward around 1.5 inches also devil wrench
Lots of ways to make any car better on the weight distribution whistling depending on how hard you want to work and how much money do you want to spend whistling work scope

Could you take a well educated guess please at the weight of my old '69 Cuda I ran back in the late 80's>1991>
unfortunately I never got to weigh it properly and was just trying to work out the motor's fwhp from mph/weight, would I be close@3300 with me being 196lbs, I believe fastbacks were heavy.

All steel apart from fibre bonnet, perspex side windows, lightened doors
6 point cage, not moly.
No inner wings, stock grill
smaller radiator, stock dash, wiper motor
stock front end+down bars
2 lightweight seats
frame ties
Backhalved 2x3" chassis
centr lines, 14x32's
440-6 block, 906's, ally intake, 4150 carb-727-8.3/4" spool
2.18" f/well hdrs
L/bars/coil-overs
large 50lbs battery in trunk+10lb N20 bottle
6 gal fuel cell, 2 x holley blue pumps.
