That low speed bucking can be caused by a lot of things. Could be something simple like incorrect ignition timing. Or a rotating assembly that's too light. You can get that from any engine, depending on how it's built, and the drive line behind it.

The Coyote is a huge engine. It's a lot wider than the Windsor engines. Getting it to fit in a car not specifically designed for it can sometime be a challenge. But it is a great engine. If the car you purchased is set up for the Coyote, consider installing it. It's a great engine for such a small displacement.

If the car is not set up for the Coyote, I wouldn't try to adapt it. It's a lot more work than you might think it is. Lots of cutting and fabrication involved. If you can easily do that kind of work, great. If not.......
