Slant Six Forum :: Clifford water-heated intake w/ Dutra duals

: Hi everyone!
:
: On Monday morning I finished up my installation
: of a Clifford Performance water heated
: intake (Clifford PN 45-4500WH) with my Dutra
: dual exhaust. I modified another stock
: exhaust manifold casting like you would for
: a Dutra dual system, but removed more
: material from the heat stove area. A plate
: was fitted to this "chopped"
: heatstove.
:
: The Dutra casting I have is Doug's newer
: casting (with the big rectangular flange). I
: had to grind a lot of material off to get
: the water passage on the Clifford manifold
: to clear it. Also, the water passage part of
: the intake had to be notched slightly (I was
: careful no to remove too much aluminum). A
: little grinding with the Dremel had to be
: done on the flanges of the Clifford intake
: to get it to clear the manifold studs.
:
: What can I say, I've never seen my engine run
: more smoothly. I still have to adjust the
: throttle cable a little (not getting to
: WOT). Now all I need is a digital camera so
: I can post some images.

: Hey Patrick,
:
: I just did a similar swap on my '68 Dart two
: weeks ago. I have both Dutra manifolds front
: and back (same casting with big rectangular
: flange), so I didn't have the heat stove
: issue. But, I too had to grind a fair amount
: of material off of both exh manifolds
: (1/4-1/2")and a bit off the water
: jacket on the intake. I also did a little
: grinding on the intake where the studs come
: through to get good alignment to the head.
:
: I had the Offy 4bbl intake on there before, and
: I still need to rejet and retune my carb for
: the Clifford manifold. So far, it runs
: great, although I need to lean out the idle
: mixture a bit. Gotta run the water into the
: intake jacket too...
:
: Cheers,

: Hi Lou,
:
: It's also a coincidence that my car is a '68
: Dart 4-door. I forgot to mention that I'm

: If your '68 4dr is medium metallic blue, then I

: does that water jacket run all thru the intake?
: If so that could be a built in liquid to air
: intercooler for a turbo or supercharger.
: just a idea!!

Hey Andrew, To answer Lou first, my car is beige...so the weirdness ends there The water heat area of the Clifford intake runs under the plenum (not under the runners) in a straight line. I'm going to see if I can borrow a digital camera to get some pictures up here. I do suppose the manifold could be cooled the same way that it's heated. Hmm, maybe when I start running a turbo...

That is something I was considering when I bought the intake. It might even be intercooled for running MP-EFI with a cooler air charge. The cooling jacket only runs under the main plenum, but a cool enough intake (using dry ice or LN2) might be worth something. cheers, Lou madsenl@its.caltech.edu

If it works, why couldn't one also use an AC system for trans cooling, p/s cooling, etc.? Then again, there might be more heat than an AC system can handle. I'm no expert, but just a brainstorm, (brainfart?) Roger GTS225@aol.com

Hi Dan, Look at the picture linked in my profile (engine bay picture). It's not the best picture. I'd take another picture for you right now, but it's raining in this part of Pennsylvania.
