I have a 1968 Mustang with the inline 6. It was my first car and I bought it in 1990 when I got my drivers license. Its been sitting, stored indoors, since 2000, but not driven. I'm thinking about getting it out of storage, doing a mid-level restoration and maybe doing an EV conversion on it. the car weights about 2700 lbs with the engine. The engine weights about 385 lbs. I'd assume the fuel tank and other accessories that wouldn't be needed would account for about 150 lbs +/-. That leaves me with a rolling chassis coming in around 2100 lbs.
I think an EV conversion would be interesting while yielding a fun car. There are a handful of lead acid battery conversions out there, but they are old tech and heavy. I've been looking for modern conversions, but they are mostly high end show cars, tech demonstrators or built for racing. They come with associated prices.
I love the idea of an EV "crate motor" for classics that can drop in without chopping up the car. It looks like we are getting close to those.
We have a classic Mini as well, but we are not ready to cut into it. It's fun as it is, but there are some EV conversions out there for it as well.
