Joe,I'm curious how critical this Heat-treating issue was before John's crash at Dallas???
Since I do a fair amount of fabrication on the side I follow chassis construction trends and rule changes pretty closely. I wasn't even aware they were using heat-treated tubing in Funny Car. The only announcement I ever remember was the changes in the construction of the back-half of the dragsters.
I'd be interested to see where the push came from to start using it on the Funny Cars!?!?
Personally, I never like the idea of the heat-treated tubing in the first place. It creates issues in other areas of the chassis.
