98mm tall. 45mm inlet 38mm outlet. weight ~ 26oz. (Ti.) PO indicates these were on a 906 & part numbers were shaved.
input appreciated.
Basically they look a bit more like a 911R Intake Manifold for a 46IDA to a 38mm intake port but the boss where the steel rod for the throttle quadrant is missing which would more like a 906 but I have never seen a 906 manifold with the centre mounting bracket.
906 Intakes tend different due to the mid-engine and the throttle linkage mounting positions which you can see in these pictures.

Original magnesium 911R castings had the numbers shown below.

There were some aftermarket replicas made in Aluminium but I am not sure if they had the bosses.
thanks for the input. greatly appreciated. please disregard my statement above "(Ti.)" i was 2 cups low on coffee. that should have read "Mag."
PM sent.
A 906 manifold looks like this (I think it's one of Armando's pics)

Bosses position explained by CHris.
I could almost swear I've seen these for sale , maybe maybe not , a pair of French guys at the swap in Anaheim last year
the material appeared way to freshly machined for mag more like aluminum, and they were painted nearly exactly as these..
They wanted I think $1800 at the time and swore they were original 911 R , well as I have an original set I was quite
skeptical , and passed ..
Looks like a set of PMO Early repros of R manifolds to me, are they for sale ?
Thanks Bert
I also understood that Tilton may have made replicas in Aluminium and a Belgian Company used to offer them in either Aluminium or Mag.
I tried to buy some for about 3 years without success and finally made our own.

the short answer is "probably". (not sure I can justify 46mm Webers for my project) @ 26 oz. and the color in the bore I'm pretty sure they're Mag.Quote:

thanks for chiming in again Chris. on mine I also note the absence of a boss to support the bell crank linkage.
Could that be because you have two right sides?Quote:

It saves making 2 x patterns.:) which saves some of the initial cost.

I've sent the PO a request for pix of these installed.
the only pic the PO could offer. they were painted red @ the time.
Sadly they still look 'wrong'
The transverse throttle bar seems to mount to the intake manifold an the end furthest from the fan and 'your' intakes have the mounting lugs for the upright in the centre which is a 911R feature.
I can't see a link to a cable or any other connection to actuate the throttle.
Interesting puzzle though.
I saw the manifolds in question at the lit meet. They looked like Mag, with the casting numbers and surface polished and powder painted. But now I see no bell crank axle. Here are R manifolds mixed in with other stuff. G.Led
thanks guys. I showed them to several others as well. Paul Bernado said they were part of a short run (10 sets or so) done some 10 - 15 years ago.
I asked if they were worth $1,000 & his reply was "...to the right guy".
These manifolds are factory 911R magnesium manifolds, modified in early 1971 by Mike Tacoma, an old school Southern California hot rodder, pilot, A&P, N3N evangelist, parts purveyor and restorationist, as well as being a germinal figure in the sport of off-road racing. That was a time when used planes and prototypes were still affordable and race manifolds only cost $157.89. He wanted the intake manifold castings to be 'Clean' so he used 911R intake manifolds with reversed 911R crossbar and modified supports. He didn't use the bell crank stud and ground off both manifold bosses. The linkage worked off the left rear using a Morse cable.
Following the brief detour building the above 906 street hot rod for his patron, Fred Davies (obviously not the contemporaneous British car constructor or footballer), he presciently left California and began importing & selling Wilgas. Even before he left the area, many people didn't appreciate hot rod 906's and the time that it took to refinish them (filled welds, smoothed, polished, chrome & powder coated castings, mirror paint), despite the many custom parts (In the photograph alone, intake manifolds, billet valve covers, progressive springs, air conditioning, even some of my billet fuel inlet bars). The special parts were out of view.
He did all the work on the 906 himself - frame repair & changes, machining, engine, trans, fiberglass, bodywork, paint, and finishing. There aren't too many of those multi-talented hands around anymore.
thanks Jimmy! I forwarded the names you mention to the PO. here is his response;
***************
Yes, car won Targa, once owned by Davies and restored for show/street by Tacoma, and sold to Mr. Bernat Chicago sold to me, frame off restoration completed to original 2006.

small world. thanks again.
