swap for a 4 or 6 cylinder engine

You can go with an aluim dart block engine but I wouldn't recemend that for a street car.

sh*t...just have the orig body banels re-cast in aircraft aluminum and gut the entire interior and just use a wicker basket turned upside down and superglued to the floor for a seat...

why are you so concerned about weight?

best bets so far would probably be an alum intake and heads...all pros and no cons to those really where as gutting the interior is going to look like crap.

Our old cars are already pretty light as street cars go, even by today's standards for aluminum 2dr coupes.

I don't see why the early mustangs are lighter then the newer ones most coupes 64-68 are under 2800lbs thats civic weight.

These old Fords are light, ours weighs less than 2,800...

Crash safety standards is one of the reasons, and chassis stiffness is another. As the federal government instituted morerigid standards for passenger car safety, the designers had to beef them to remain compliant, and the use of unibody meant adding more panels to make the car safer. They've also been changing designs over the years to make the cars stiffer, to better transfer weight and power during cornering and acceleration and breaking(ie, adding more reenforcement). Then when you add on top of that, the fact that they add more insulation to cars these days to make them quieter, plus the extra weight from all the wiring in all the various electrical systems. Cars just have more stuff in/on them these days, and it all adds up. Now with the use of computer aided design, and decades of engineering, they've learned where they need the metal, and where they can take it out. Some new cars are quite light, Corvettes for example these days have a curb weight of around 3,100lbs, new S197 Mustangs are like 3,450. Our cars varry, big blocked fast backs could weight in as much as 3,500lbs, and low optioned I6's could weigh as little as 2,600lbs. In the end though, most 60's era American V8 cars have a few hundred lbs advantage over your average current passenger car with 2drs and a V8, or even a 6er.

Remember though, you need to compare equivalant cars to have a good comparison. Trying to compare a steel body V8 car from the 60's to a plastic body sub compact I4 car from today isn't fair. Still though, I do like when ricers go "Yeah, well my car weighs like 700lbs less than your's!!" And I respend with "Yeah, if I had a dead horse in the trunk."

Here's a goodcomparison, take the big blocked fast backs of the 60's, at around 3,500lbs, and compare it to the modern equivelant car, the GT500, which is hard pressed to remain under 4,000lbs with a driver and a tank of fuel. Curb weight for curb weight, the heaviest 40 year old Mustang is about 200-250lbs lighter than it's modern variant.

Even current Porsches and Ferraris, which are obviously built mainly of aluminum and lightweight composites, come in anywhere from 3,000-3,500lbs curb weight. You have to get a super exotic to find a high performance car that's under 3,000lbs these days, and it's prolly gonna be built mostly from carbon fiber based composites and cost a LOT. Even the Enzo has a curb weight of just over 3,000lbs.

By modern standards, on average, our cars are on the light side. Yeah, there are lighter, but there are also heavier. But for a RWD V8 metal car, we're hardly fat.

You mean like this?

That, btw, will pretty much disallow you to run at any drag strip that follows NHRA rules. It's classified as compromising structural integrity, and is an automatic tech failure.
