Pulley troubles
And my old one:
(The extension piece is warped which is why I was intending to replace the pulley. Maybe I should just replace the extension it's self and re-use the 2-groove base pulley?)

63-74 small blocks used GM pulley 3751232, and 75-82's used pulley 346290, later replaced with pulley number 14023153. The "232" pulley is still available from Chevrolet for about $55, but I think the 75-82 "153" pulley has recently been discontinued.
Then, if the add-on pulley is distorted, buy a replacement for just that.
