1969 Valiant 4 door Gas Sipper

I'm planning on building this house-paint-covered gem into a little gas sipper/daily driver. The 225 in it is no good, but I have a 170 to swap in. The car is out of Alabama and I was told by a previous owner (are you still out there? I lost your contact info) that this car was a runner when he sold it just a few years ago. However, the kids that bought it from him revved it to destruction while trying to leave his place! But before they goofed, he had already done a lot of the little things it needed to run. So I'm thinking with an engine swap and some wheels/tires, that it isn't very far from being a driver. One puzzling thing is that it sits on a bunch of trailer tires??? I get that they: might have been the only 13s available at some Walmart somewhere, or were just laying around, or are just rollers... but was it really driven like this?

Also, what is the best way to remove latex house paint from a car while preserving the underlying original paint? I've heard of several methods online, but I was just looking for advice from you guys in case there was some magic concoction that works best on Mopars that I don't know about. That orange stuff sounds interesting...

Here are pics as she sits, covered in Glidden premium (maybe). And sorry, the gold one is gone now.
