NHRA STOCK CLASS DUSTER

I talked to a guy at the Mile High Nationals about running a 360 power Duster in Stock and he said that they are not nearly competitive enough.
.
That's interesting. I talked to a stocker at Mopars at the strip about the 360 and the 340. He runs a 71 340.
And he told me the 360 had a little more bottom and had a tendency to break things before the 340 did.
I guess I'll find out the hard way. Either way I wanted to race stockers since I was a teenager.
