5 to 8 point is legal to 10.0. I have a 5 point roll bar in my pinto. A roll cage is 10 points and needed under 9.99.
NHRA
ROLL CAGE
Roll cage mandatory in cars running 10.99 (*6.99) or quicker or any
car exceeding 135 mph. 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. In convertibles running 10.99 or quicker or
exceeding 135 mph, roll cage mandatory. Cars running between
7.50 (*4.50) and 9.99 (*6.39) must have chassis recertified every
three years by NHRA and have a serialized sticker affixed to cage
before participation. Plating of chassis prohibited for all cars
manufactured after Jan. 1, 2003. Rear-engine dragsters must
conform to SFI Spec 2.7B; vehicles running 8.49 (*5.35) to 7.50
(*4.50) and/or exceeding 180 mph must meet appropriate SFI Spec
for body used. Effective Jan. 1, 2007, all new Street Roadsters must
conform to SFI Spec 10.4. Existing Street Roadsters must meet SFI
Spec 10.4 at their next scheduled recertification effective Jan. 1,
2008. No existing cars will be recertified early to delay compliance.
All others must conform to specs for body style used, as listed in
General Regulations 4:11, 10:6.
^^ there we go. Thanks for the info. I found something similar online today too. The list you posted is more comprehensive. Cage & bar... very different. So I'm thinking cage now so I have room to play.
^^ good idea. I need to make up my mind if I'm going to end up competing in events with this project. I would like to support the OSCA and get involved in the organization. Just not sure what class / index... My ultimate goal would be EZ Street but I'm worlds away from that level. Open comp ? 10.99 index? I want to try the 12.90 index with the 99GT next season.
I will probably step it up to the 11.90 index next year.......so that should give you something to shoot for Andrew.

^^Awesome... I'm pretty sure when I spray the 99 it will be there. I'd need some weight reduction & a stroker to do it N/A.
I hope we get to hit the track together MANY TIMES next season. I'm looking forward to seeing what you have up your sleeve. This is going to be fun!
I will start a build thread for my new pushrod setup for the Mach 1 chassis once I get more parts assembled and begin working on it. I'm thinking of going with AFR 225 or 220 heads or TFS heads of the same range.

I have a 351W block and will be taking to the machine shop when I decide on and purchase the rotating assembly. 408 - 427 stroker.
