Cam Choice for my 66... b303 or e303?

[Sierranevada1]

Looking to give my 66 that sweet "cammed" idle.. Its a 93-95 5.0 crate that's carbureted w/ headers, intake, 5-speed manual, & a power brake booster. It's no race car and she runs good but I cant stand the stock idle... Any recommendations??

Ahhh, that sweet ra-chachata exhaust note. I remember!!
Have you looked at any others?
Any other info?
