Father in law passed a few years ago and we are finally clearing his house out. He told me he had bought a 6pack intake for a slant 6 when he was in Australia, but I never saw it till now. Can't find much info on it and whether its worth selling or not. Any Info would be appreciated.

Looks like a triple Weber intake with a set of Durra Duals. The last time I checked on the OZ eBay a ttiple Weber was going for 550 to 600 Au$

There weee several companies besides Cain making the triple Weber (and triple SU intake).

Dutra Duals go for $900 a pair . Many use 1(rear 3 cylinders) and cut the front stock manifold using the front 3 cylinders.
As stated above triple Webers intake is easy a $600 item.

Yeah he only bought 1 exhaust, guessing the rear...
 
That CAIN intake is between the short Clifford and the longer Redline intake.
It was an Ozzy part years ago.
I had one and sold it to a street racer from NY City.

Can you measure the runner length from head face to carb bases?
Problem with Weber intakes is, they look cool, but few folks have the cash to finish the install.
And used Weber carbs are no bargain.
A 45 DCOE at Pierce Manifolds is around 500 dollars. Times 3.

6 1/4 length
 
My Weber measures 4.5 inches from head to carb bases.
Also I don't see any linkage in your pictures.
I see the towers that would hold the cross bar.
 

Australian Cain weber DCOE manifold probably from the 90s or early 2000s

boses to mount linkage....undrilled

recent redline version here to give you an idea of cost before export and tax and shipping

Chrysler 225 Slant 6 Triple DCOE Weber Manifold

would work well with 3 of these

i built my linkage for my hemi 6 version using hex bar mounted between rose joints screwed onto studs at the 2 end bosses.
converted my webers to left hand side throttle arms and used the half inch hex bar, Cast offset linkage arms and throttle pull from here.

Steel Hex Cross Bar (specify size)
Just picked my parts from the catalogue rather than take the VW bug kit
i drilled and tapped the bore of the hex bar to allow mounting between the joints. big bolt and lock nuts up each end....
i also used CB performance DCOE filter bases and Tops and their "decent" filters.



basically you have parts there to make up the basis of a very nice induction and exhaust kit for a warmed up slant 6.
that set up with the right cam would allow easy operation at a higher static CR than you would get away with on a unequal length runner distributing manifold.
you could turn an already torquey motor into a right good stump puller
and based on my links above it would not be too expensive to do it.

The chinese carbs have a decent reputation (in this case)

oh and yeah short manifold just use longer ram tubes, long manifold just use shorter, its the tuned length of the lot that counts. you have loads of space on a slant Its not like the carbs will hit the inner fender....

If sand in the casting was such an issue, you'd think they could take 10 minutes with a Dremel grinder and clean it out, rather than taking the lazy way and putting it on a tag for the buyer of their really expensive part to deal with.

Thanks for the info Dave......

I think they put that tag there to cover their *** and make sure you clean it out.

Australia isn't as litigious as the US but the consumer protection is stronger in many ways

in that the context........ you can fully expect someone to have had an issue and taken someone else to court over it. Hence *** covering label on the manifold.....

on the other hand most aussie made parts are usually of good to excellent quality...small market, limited audience for your product, and you name can be ruined in double quick time. so the chances of spending a lot of money on something utterly useless are reduced....

Yeah casting is very good. I see no issues.
 
Got ya, just dont understand why he would buy a front and not a rear...
It was initially done utilizing the rear half & outlet/heat-riser part of the OE manny, the front leg & runners were cut off, and a plate welded over the opening there. This way you could use all of the stock features, equipment, & heat to the intake. Dutra cast the front piece and voila, dual outlets, freer flow & the ability to tune the pipes for best torque/scavenging.
