I ran a lunati bracket master cam in one of my BBC's (396) it was ok, nothing to brag about, ended up swapped it out for a CC after it rolled a few lobes.
I ran a simlar set-up as you, I ran a comp cams 305 magnum in my 358 SBC, it ran like a scaled ape.
IMO, You need more compression to wake your combo up though.
Goodluck, Cp
