Does anyone know at what et what equipment is required?
Im hoping my 69 camaro vert w/ modded LS2/T56 with drag radials will run a low 12 or maybe a high eleven if I'm lucky. Thanks
I did a search and it was old info, things might have changed.

13.99 or faster needs a roll bar. I think 4 point is ok to 11.50. You need a 4pt harness, and a snell 95 helmet, and reverse lockout.

This should help: http://www.nhra.com/tech_specs/ETQuickRef.html

yep that is what the link says, "C/13:49" next to roll bar even though it is in the 13.99 column


how do we find out the #of points & tube thickness, etc.. & is 4:11 the section in a rule book?

Don't have rule book, but the 13.49 number stuck in my head from past research because I just finished a 6 point in my 67 RS Conv.
