Get a rulebook for sure. You can’t use a “bolt in” rollbar in NHRA competition. Plus with a full frame you must cut holes in the floor and the bar must be welded to the frame. You will also discover the torque from the big block will want to flex the frame. There are bolt on frame stiffeners and boxing the frame helps a ton. You will also not want to use a 396 block either when searching for power. A sleeved back 454 or aftermarket block is a better investment. Good luck with your build. Do lots of research and save money. Oh and R&D for sure! (Rip-off and duplicate) lol. Just my .02 as I have been there done this.
