Phil,
It would be a sad day when you and I cant compete in the same class.
and would probably be the year I stop going to the Nationals.
If you look at last years results for class 3 there is definitely no advantage in being powered by the dark side and the top 10 with a good mix of both motors were only separated by 3 seconds. I expect that the 3 second difference is related more to experience,tyres and chassis set up rather than power.
Part of the fun is the GM/Ford rivalry which from my perspective is all tongue in cheek
But it will be a good day when an LS powered Cobra takes out class 3
