I've heard that the 70-71 240z's are around 2200lbs and that the 72-73's are around 2400lbs.

if this is correct, then what exactly made up the extra 200lbs in the newer 240z's?

though i havent weighed my 71 yet. but my 72 240 which had the 2.4 block E 88 head, no bumbers front or rear, 5 speed tranny, fiber glass aero kit, with full interior and 215 60 14 tires, weighed 2300 on the scale even, tank was about 5 gallons. thats just the car. no driver.

im going to take my 71 hopefully down tommorow and see what it wieghs in full stock trim.

what i think really made the difference was thicker metal and more sound deadening for the 72 and above.
