Ok - There's so much info on this, but I can't seem to get a definitive answer.....I'm easily confused...lol.

06A - SS350 with cowl induction --  Flat or ridged bottom?  That's all I need to know.

Thanks!!

I think flat, the ridged ones showed up later in 69

Flat. The other style didn't start showing up until August
