Was 3700 with full interior/stereo, multileafs, stock 4 core copper/brass radiator, TH400 and all-iron big block.

3200 with Aluminum 5.3, heavier 4L80e, tubular control arms, aluminum radiator, replaced traction bars with caltracs. Probably around 3300 with turbo setup now.

Thinking about getting TCI front subframe, fiberglass bumpers/trunk, and maybe rack and pinion conversion. That'll put me down around 3000.


I think the car was around 3450 years ago with a small block. Car has always had full interior with stereo and stock seats (buckets up front).

1973 4 door with a carb'd iron block 5.3, th350, fiberglass hood (saves 40lbs!) full interior, stock suspension and about a 1/2 tank rolls across the scales at 3260lb not including driver.

That sounds right in line with Hexenlord's 3200 with an aluminum 5.3. Next thing to go on a dieat: ME!...Cheaper then fiberglass parts

Mine was 3180 without me, bench seat, all-iron 350/TH350. Now iron-block LS with T56 and Corbeaus, I'm sure it's a bit less.

FWIW, here's a list of 3rd-gen curb weights.

Per the Factory Service Manual, A 6cyl is 3028 lbs. and a V8 would be 3169 lbs. These would be Base Model weights.. you add in from there..

Also remember most old engines were iron heads and iron block... I do not have my car together but I expect with my ly6 and 4l80e to be around 3200 lbs

yes, I gave those number as a base line as it left the factor, up to you to add or subtract weight for your build, trim and accessoies. At lease a good guees to get you in the ball park.

knowing a sbc gen I is about 80-100 lbs heavier than a gen III/IV.. that should give you something to figure from.

69. I'm hoping to one day get below 3000 lbs without giving up too much in the interior. I would like to keep full interior, with dynamat on the floor, with speakers, and maybe an 8.50 cert cage. It'll require fiberglass bumpers, hood, and trunk. Aftermarket front subframe with tubular control arms and rack & pinion conversion. Lightweight (lithium) battery, and lots of replacing other factory parts with lightweight versions.

I've done quite a few carbon fiber projects and have quite a bit of it in the garage. I might make molds for carbon inner fenders as there is another 25 lbs to be lost there (and TCI subframe comes with brand new aluminum versions just waiting to be molded).

I don't think it will be too hard. Weight wasn't a concern when the older muscle cars were designed. That's why factory subframes and control arms are so huge and heavy, and everything else was stamped from heavy steel that rusts so easy.

Ohh forgot to mention I removed 60+ lbs of the original tar/paper insulation that was originally in my car under the carpet. I also have replacement chrome bumpers and they are lighter than the stock bumpers, also aluminum rad etc etc. That is why I said about the same as stock. I was also judging by a car based on a 69 Nova (Mine is a 68) and was just over 3140 lbs at the scales with a 383 sbc all iron except intake (l31 vortec heads).

So then you take that base weight and adjust for the last 40 years:

-If your Nova is from the Northwest you add 20LB for the pine needles and moss that calls your car home now! (From personal experience!)

-If your Nova was from the Southwest you ADD 30lb for sand that has been packed into every crack and seam on the car.

-And finally....If your Nova as lived on the East coast or Midwest; you can subtract another 50lb for body panels and parts that that were claimed by salt induced rust!
