I will soon be building a roll cage for a customer. I am needing to get information on how to certify the cage. Its going on a nbs s-10 with a big block. I don't have all the specs on the engine I just know he's pushing well over 500ci's and has plans to be deep into the 7's. Any info will be greatly appreciated. Thanks, Preston

The NHRA rule book also explains roll cage specs. & how to get it inspected.

Good Luck!
