Here's a bit of trivia - FWIW the manifold was the 351c FORD Intake manifold known as a (4V GTHO Buddy Bar) 351 D1ZX 9425 DA used on our Legendary Phase 3 GTHO Falcons in Australia - back in the day.
I bought an XA GT optioned RP083 in early '74 with this very manifold and it had a bunch of other stuff from our cancelled GTHO PHASE IV program. Various people in our GT Club said it was a '' ring in '' and shouldn't have been on the motor, so I removed it (kinda reluctantly ) and put an iron 4V manifold in its place. I've owned the Red Pepper GT since early '74 and it hasn't seen daylight for 45/46 years with 40,000 miles on the clock - due to losing my licence so often that I had to appear before a committee to asses my psychological profile for holding a driver's licence. I had to prove that I'd removed the engine, broken it down and stored it in a 44-gallon drum of oil and cancelled the 'rego on the GT to keep my licence at the end of a 2-year suspension. There's a YouTube video of an XA idling which could be a clone of mine - mine has a parchment interior and body every bit as good. I still like taking corners sideways, so the GT stays under covers.
Here's a couple of links if you're interested in our XA GT's
