With virtually no seat time on the new combination, they walked straight into Hot Rod’s Drag Week 2017 chasing a record, and immediately ran into wiring harness gremlins that nearly derailed the entire attempt. See how a team with no playbook turned a fresh, largely undocumented engine build into record-setting territory.
