Glidden Arrow

The fact that they were using cast iron heads and blocks probably reflects the time and maybe the rules of the class more than anything. "Pro Stock" meaning some part of the deal had to be a factory part. Ultimately he did what he did because that's what the technology of the time allowed. CNC machines didn't exist, nor did CAD or whatever. There were aluminum blocks and heads for some stuff like top fuel but pretty sure no one was making alloy heads or blocks in an effective race configuration for small block Mopars.

It's just neat stuff from a long time ago. Makes you ponder what he would have been able to accomplish with the stuff that's available now or even a few years ago. Computer deigned aluminum parts levels the playing field but at the same time eliminates the uniqueness out of specific platforms like small block Mopars of Clevelands.

That's progress I guess and probably why we have nosalgia racing classes.
