I have an original steel floor, firewall and body 1985 Camaro that I’m building for Pro ET. It should run in the mid-10 second range. Do I need to install a complete roll cage or will a roll bar suffice?

Roll Bar Ralphie,
In your application the roll bar will work just fine. In the 2013 NHRA Rulebook, ET Section 4A, page 5, Roll Cage it states “In full-bodied cars, with unaltered firewall, floor, and body (from firewall rearward, wheeltubs permitted), running between 10.00 (6.40*) and 10.99 (6.99*), roll bar permitted in place of roll cage.
