An old post revived.
Let me just add that shipping weights are for the lightest, least well equipped models. I.e., Barracuda V8 shipping weight would be for a 273 or 318 (depending on year), three speed manual trans, single exhaust, 7 1/4 read, no PS or PB or A/C. At least I think that's right.
Anyhoo, my 67 Barracuda notchback, 360/727, 8 3/4 rear, aluminum intake, iron heads, TTI headers with 2.5 inch X-pipe exhaust, manual steering, manual disc brakes, no A/C, bench front seat with fold-down armrest, 15 inch Cragar mags, front and rear sway bars, all factory glass and trim - weighs 3400 lbs with a full tank of gas, w/o me in it.
My 65 Barracuda, similarly equipped, except 340 4-speed and aluminum heads (plus bucket seats), weighs 50 lbs less.
I was at a drag strip quite a few years ago, weighed my 65 Barracuda, someone came by and said, "Wow, that's heavy!" I thought it was pretty light (my 67 Hemi Charger weighs 4100 lbs), but what do I know?
