I've been using a 454 big bock lately. Thinking of getting a second.
Running that on a vvg? Did you have rob do a mech conversion? I've been thinking about sending one of my vvgs to get the LP haircut, but I doubt 15 watts will be enough to run dual coils on the larger atties. I'm typically running duals in the 0.4 range on mechanicals. Might have to get a 510 Adapter and see how it feels.
