To Quench or Not to Quench?

Yes. Sorry. The correct upper arm. lol That would be for instance 73 and up A body disc brake arms.

...and all this slant six blabber got me motivated. I went out and pulled my super six down to the short block. It's a standard bore cast crank engine....so it's an original super six. They were all cast crank motors. Fine with me because the cast crank is actually lighter. lol I certainly will never push its limits in a rat rod. I may get the rest torn down later this afternoon. Gotta rest a little first.
