>>>*Beats me on that, Kevin. Interesting, tell us more. It's not something I know a he** of a lot about, it was THE process in the 70's and 80's. Heating the rods was to be done slowly and for a long 8 hour period at 450?. We just left the oven door shut until they were cooled off enough to handle, and when done a file would slide on them unless we used a lot of pressure. Most rods are steel of course. Now we just repeen them after grinding, that is lots faster, all it does is stiffen them some.

The process was from an article written by Smokey Unick way back in one of the hot rod magazines. When I was a kid that man was THE word on racing tricks and I never really questioned that since it seemed to work. We never broke any, but now that I think about it, we weren't breaking any anyway...*LOL**....

But I am interested on serious cooling, I was poking around on Google and there are lots of claims but not a lot of real info....*EB
