Sure. Did a lot of 10.0 index racing on a .400 pro tree with in a points series, and no box bracket raced it.
Uncut, untubbed 70 Duster on 002/003 leafs. W5 deal.
New owner still races it.
Building something similar to go in my 69 Dart as we speak. Wont be as stout, probably 10.20-30 car. But it will log street miles too.
