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.

That’s all the I have I’m afraid.
Kind of small for the controller. Maybe DC-DC converter. Do you have a photo from the other side? Let's see if he is cooling this valve cover.
I’m thinking controllers may live under there...maybe.
You gotta to love the addition of that original valve cover. That's great.
I’ve watched Rich‘s stuff. He’s entertaining. The Mini was interesting. We have both a classic and a modern R53 like he worked with, so it’s not too far off.
someone posted this pic on a classic Mini forum group that I’m a part of. Someone is building an EV, using the original transmission and trying to make it match the original style.
yeah, check out Rich Rebuilds on YT. He just did a Mini a few months ago. It is a conversion he did for $3,000. It was more of a challenge than a bona fide conversion. We have quite a few conversions in our Electric Car Group. Electric car clubs are quite popular in So. Cal. With the prices of batteries coming down, and controllers and motors even on eBay, it is a fun project. V-8 electric crate motors and differential motors make things a whole lot easier. One just has to decide whether to keep the transmission or not. Part of deciding a donor car is the relative value of the car. Restoring it with a numbers matching motor ICE vs a modern conversion would result in a fairly different value after the restoration/conversion. Only you will enjoy the work you put in. Have fun!!
