I haven't weighed, but simple driving tells me my 73 Vettes are at least 10-15% heavier than my 69 Camaros. The biggest difference has the be the full frame/birdcage vs. the unibody. Secondary factors are the IRS, front bumper on my 73, 4 wheel discs brakes (vs. front disc, drum rear on the Camaros) and doors.

You'd think a two-seater fiber-glass car would weigh less.

But the Vettes win the weight distribution contest, hands down!...this is 'somewhat' important as well.

get rid of that spare tire and carrier. then put aluminum heads and hooker side pipes also a non stock hood will save about 40 pounds too. . then pick up a small electric tire pump and patch kit
i kept the jack , i don't know why? store all of that in the doors of the floor behind your seat more than enough room also have the jumper cables and hand tools just in case . 72 vert still weighs just under 3150. if your going to drag it behind a trailer don't worry about the weight

The fiberglass isn't that light at all. I could weight the front and rear clip completely, the weight would be a tad too little as I cut off some pieces in the back and don't have inner fenders on my front clip. The rear glass (bubble glass) is very heavy as is the windshield.

The floor is pretty heavy too, the birdcage itself dunno...I can weigh that also. All these pieces however are easily carried by 2 people. probably also by 1 person but too large and cumbersome to handle

My white '71 LS6 coupe in absolutely stock condition, weighed at scales and certified the weight. Came in at 3340lbs, with no fuel in tank, well virtually no fuel (was running on fumes, practically) and no one in car.

I'll probably just weigh it anyway, hardly any trouble. I have the rear clip off and the front clip also. I'm curious as to how much it really weighs.

My PT Cruiser weighs more than my '80, I don't think they are that heavy when you start comparing, it also weighs about as much as a new Z350 too

i took exactly 650 lbs off my vette...so i should have well over 100 hp of power to weight savings achieved, on top of the 570hp of the engine itself

it's not only a power to weight iussue...a lighter car brakes and turns on bends better then a heavier one...so not only it's faster but it's also more driveable

I've heard said that on a typical street car, every 100 lbs is worth about tenth in the quarter.
