Captain Jack's Speed Equipment is home to a growing variety of vintage speed equipment. We manufacture, buy, sell, trade early speed products. If you are one for keeping the flatheads and inlines alive, you'll like what you see. Just like Route 66, the flathead V-8 has passed from legend to obscurity. Captain Jack's line of vintage speed equipment is intended to provoke renewed interest in vintage engines, like the flathead, so that it's rich, mellow thunder shall not perrish from the earth.
