Interesting intake manifold.

Some kind of experimental part??

My guess would be old can-am stuff for side draft carbs of Hilborn style EFI

Looks like a one off piece to me check out the casting flash in the thermostat well. blueing on the one inlet side shows someone was trueing the surface still. Bosses on top aren't drilled yet either. I'd love to get my grubby paws on something like that

I think it may be a newer casting than the old trans am stuff due to the bosses on top and also looks like another set of bosses on bottom by the flange. I don't care for the S curve in the runners, not sure what that does to the cross section there either. I think it would be a cool piece for maybe a kit cobra or show car but not on par with a good single plane. Wonder about the port exit size, wish there were pics of bottom side.

Edit: Would probably be good for twin turbo set up with a log type adaptor on each side

Would not need throttle bodies as it has bosses for the throttle plate shafts. Interesting looking piece. Lot of work still left to do for it to be usable.

Just taking a closer look. It would have to be for 90 degree mechanical injectors. If I was having an intake like that cast for EFI I would have designed the bosses so they were angled toward the port. It could still be used for EFI just more work to get the injectors aimed correctly.

Someone had to go thru the trouble to make a casting mold for it. I wonder if there are any finished / running units out there in service somewhere!! ....or what brand it is!!
