Biggest engine you could ever get in a Gremlin was the 304 V-8.
This one was a 232 I-6/Automatic. It was still running well when he dropped it off, but it had a lot of other issues - brakes, rust, etc....Yo can see in the pics where he and my father touched up the surface rust ever year, but you can also see that major 'rot' had set in on the bottom of the doors, under the chrome trim strip, and behind the back tires. AFAIK, the floor was still solid.
The car eneded up stitting in the spot you see it in for about 2 years. My dad drove it a couple of times when he needed to do something specefic (it picked up an X-Mas tree one year), but beyond that it didn't go far. We ended up selling it to someone who needed a cheap winter car. I wanted to keep it, and learn to fix it up as my first car, but my dad wouldn't let me.
This is where my love for AMC's came from...this little orange car.
