If this is in fact the case (talking Stock) and with the recent difficulty in getting the "aftermarket" heads then the Racers should not have any problem with NHRA removing the "aftermarket" heads from the accepted lists.
Maybe they (NHRA) could use their recently enacted Rescission policy!

What class factor is required for a combo to be obsoleted from Stock Eliminator?

I understand that 7.50 is the factor for AA....but can the combo be any amount under 7.50 and still be allowed to run AA?

Or what is the lowest threshold class factor still allowed in stock? Is a 6.95 class factor allowed to run in AA still?

Not sure I'm on the right subject here. Check out the 71 440 6bbl Roadrunner. It can run A/SA. AA/SA with a Hemi. It is also a natural E/SA with a 340. Some weight got trimmed off that car. Cool makes a new combination in lighter trim.

Hopefully the Mopar big blocks 6 pack combos can get an HP break so we can keep up with the others.
The cars have to weigh almost 4000 lbs
Trying to run with cars that make the same power that weigh 3400 lbs.

It's now like taking a knife gun fight.

So how does the AMA car weight work? I looked at 1970 Plymouth 340 Duster AMA specs. It shows shipping weight at 3105lbs and curb weight at 3269lbs. I get an average of 3187lbs and NHRA shows the shipping weight at 3186lbs. Is that the method or just lucky on one?

I was told shipping weight. All the curb weights are the same on the AMA Sheets for a 70 Cuda, 340, 383, 440, and Hemi. I wonder how NHRA verified the weight of one Cuda with the 340 to the weight of 426 Hemi Cuda?

How many almost free SS Pontiacs were given out back in the day. Div 5 had a few after a trip to FJ?
