One of my friends said it best about the 509 cam, "baddest cam at the drive in".

If you want something that really sounds tough, and is low effort and easy on parts, that's it.

But......... Anyone priced one of the 108lsa versions lately?(P4120237AE)
Last I saw, the price reflected what I can only assume is FCA thinking, "we don't want to sell these anymore".

If I were to recommend an off the shelf grind that fits the same application criteria as the .528 cam, but would have a little rougher idle, I'd say the Hughes 4246.

For a real "street" cruiser though, I'd use something with less lift and smoother(slower) ramps that could be controlled with less spring.
Something more like the 528, but on a tighter lsa to put a little more "pop" in the exhaust at idle.
I haven't seen anything like that in a catalog, so it would likely have to be a custom.
