Anyone tried one of these HEI Distributors?

that's the distributor I have on my Duster- my brother got one for one of his barracudas, and he liked it so much that he put them on ALL of his cars. Even bought one for the 440 he's building for his sport fury 'vert, now that they have a BB version.
Works great, but you need good voltage to get spark on startup (I think my bro said it needs 12.6 volts to spark).

We also tried one on my Scamp a couple years ago, and spent quite a while trying to get it to go, with no luck. My brother finally pulled one out of one of his cars, and my Scamp fired right up- the first one we tried was DOA (could have been the issue for dustermaniac).
