Dimitri Toth tells me the factory made slightly more that forty in either two or three (I don't remember?) pourings. He said some (or all I don't remember that either?) of the SD Lemans/Tempest came with 859 setups on the engine and the bathtub in the trunk. I have both a factory and a repop and will try to remember to post pictures of them here. The repop is better IMO because the runners are thicker and can be ported more and because they do not have the two barrel idling carb circuitry in them, which is unnecessary and only catches condensed fuel laden air into pools of asphalt like gunk if those circuits aren't relieved, and as Tom said also don't have the plenum problem as bad as the real one. Whew what a sentence! But the lettering and casting #s are much more distinct on the real ones.
