For those who came later>
Some time in the late 80's ,the roll bar rule for brackets was 11.99.
For Stockers, it was down thru J & K
Gen 3 305 cars started to get popular, the hp factors were pretty low, and some could run in the high 11's in L, M, N, etc.
Guys would show up for test and tune with no bar, by the Stock rules and the local bracket tech guys didn't know how to handle this. The bracket guys would complain because they needed a bar in the 11's.
NHRA, instead of using the ET as a guide, just jumped in and added L&M roll bars to the rule book .
Not long after, the bracket roll bar requirement went down to 11.49.
The 305's got hp added to where they could run F&G and run pretty close to, or in the 10's.
I brought up this inconsistency to Bruce, several years ago. He listened and said he would bring it up, but nothing ever happened with it.
So now we have M cars at Denver in the high 13's that require a roll bar but 11.50 bracket cars that don't.
I know we lost a few good class racers because of inconsistencies like this.
We probably lost a few beginners too. But does NHRA care,...Nah
