Note the cam in my '67, in my signature. It was a SFT from Bullet, using UltraDyne lobes. 247/247 @ 0.050, 108lsa 109icl. In the .060 over 455 I had, that motor ran best shifting at 5900rpm (and I crossed the finish line at 5700). That cam gave up 60' time, compared to the HFT 231/239 @ .050 I had previously.
If I still had the car/motor and was putting in a new SFT, I'd probably drop about 8 degrees off of the intake and spread the LSA a bit more.
