Don Teifke was hunting for a donor Mustang to support a future Factory Five Racing Mk4 Roadster build when he stumbled on this second-generation Mazda RX7—a car he always liked the look of. His brother had owned a 1986 GXL RX7, and Teifke liked it. But it always needed a V8, he said.

When he stumbled on this RX7, the paint and body were perfect, but the drivetrain was a little rough. The only responsible choice was to drop a small-block Chevy 383 stroker into it. And Teifke makes responsible choices, so that’s what he did.*

The net result is a car that runs 11s at Great Lakes Dragaway, and presumably serves as a pretty cool sleeper on the streets of Wisconsin, where Teifke makes his home.

This is a super-cool swap, Don. Thank you very much for sharing with us.

*This is pure speculation. Teifke could be a total loose cannon. We just know if you’re dropping bored and stroked Bowtie motors into Mazdas, we’re always going to give you the benefit of the doubt.
