That's a dual-distributor setup. My head ain't believin what my eyes are seein. In order to use this, you'd have to have a second gear at the front of the cam and two plugs per cylinder. The last time I looked at a smallblock head, there wasn't a heck of a lotta room to put another spark plug orifice. And I don't see anything that looks vaugely like 2 plugs or 2 wires near each stock location.
Admittedly I haven't seen anything like every setup that's available but what I HAVE seen is show cars with a lotta non-functional stuff on them to look kool.
Ok. So I called the salesman and he said it was a "special race car setup" that used a special timing cover and a gear that bolted on to the front end of the cam to drive the front distributor. He also said that the rear distributor is not being used. There's only one plug per cylinder. He suggested removing all the trick stuff and puiting a stock timing chain cover on and then using the rear distributor only.
I sure don't think I'd pay $30 grand for it. Especially with what appears to be puke-green variegated shag carpeting from the 70s.
But they say that there's an *** for every seat.
