Stock K frame?
Currently, probably the Kevco, like Rusty said.
All-time best (for bracket racing)?
The Milodon Super Stock 9 quart pan, with some caveats.
First, it's no longer produced. Hasn't been for quite a while now. Still highly sought after, so good luck finding one, and $$ if you do.
Second, it requires it's own specific oil pickup, also unavailable new.
Third, I'm not aware of any version made for the 360, only the 340/318/273. The rear pan seal is the difference (smaller on the 360/Magnums), although I have seen guys make a spacer for the pan and use the 360 rear pan seal. I'm assuming your 408 to be a 360/5.9 based engine.
