I haven't personally used the Chinese HEI distributors but a couple guys I build motors for have. Not sure if they even fit in an A-body car (its tight in a B-body so I kinda doubt it). This guy used it mainly because everything is self contained so all he needed to do was connect 12V.
I like stock looking stuff. The buyer had a choice of an old style mopar M1 dual plane intake or this airgap. If it were me I would have used the M1(it is basically a slightly enhanced stock 340 4bbl intake cast in aluminum) and a mopar ignition along with some stock valve covers (stock LA valve covers can be used on magnum heads with very little work. The five bolt holes line up perfectly) Paint the whole thing red and you have a stock looking 318.
Good info. Seems like the Procomp HEI works well enough for him. I had to go back and watch it again to make sure I was seeing what I thought I was seeing.
