Re: piping heat into clifford performance intake
My Clifford intake manifold had the water inlet & outlet on a plate
covering a small hollow area on the bottom of the manifold.
You can either run a short piece of metal brake line from the exhaust
manifold to transport hot air to heat the manifold or you can route a
coolant line through it as I did. My Weber carb has a coolant
controlled choke so I routed it through that as well.
I went from a rough running motor with ice forming under the manifold
to a smooth running machine.
When its really hot out it acts to cool the intake manifold and
prevents it from overheating.
I ended up taking off the manifold to see the hookups underneath it.
Once off it was easy enough to see what type of adaptors were needed.
You may find the heat riser line from the exhaust manifold sufficient
for your needs and a lot easier to engineer.

Re: piping heat into clifford performance intake
Someone else mentioned that the water jacket holes are in the bottom of
the manifold. They sure aren't on top like a stock one and don't appear
in your photos. If they are there, then likely they just need a plug
unscrewed and an adapter screwed in to fit the heater hose to. It will
be a standard pipe thread adapter, 'likely' a 1/2" one.
Then the top heater hose (top of t-stat housing)loops over and goes to
the front of the manifold and continues on out the back of the manifold
and up over the valve cover to the heater core at the firewall.
Even with the warm water in the manifold or in the carb base, sucking
fresh cold air will cause ice problems. As the air speeds up going down
the venturi, it condenses and causes ice.
That is the big issue with that 'off road only' air filter you are
using. It has no place to suck hot air like a street legal air filter
has. I have had those freeze on several occasions. Forget 'several',
change that to 'tons of'.
Nothing like having the rpm stay at 3000 and opening the hood to find a
block of ice where the carb should be.
A proper air filter has a vacuum and thermostat operated bypass that
sucks warm air from the exhaust pipes until the air inside the air
filter is actually heated up. You can make an air shroud out of a chunk
of tin or sheet metal for the hot air intake on the header and just use
a couple muffler clamps to hold it on, but you need a proper air filter
to use it.
Maybe get a 'winter' air filter and keep the pretty one for summer off
roading?

A proper air filter has a vacuum and thermostat operated bypass that
sucks warm air from the exhaust pipes until the air inside the air
filter is actually heated up. You can make an air shroud out of a chunk
of tin or sheet metal for the hot air intake on the header and just use
a couple muffler clamps to hold it on, but you need a proper air filter
to use it.
Maybe get a 'winter' air filter and keep the pretty one for summer off
roading?

the manifold. They sure aren't on top like a stock one and don't appear
in your photos. If they are there, then likely they just need a plug
unscrewed and an adapter screwed in to fit the heater hose to. It will
be a standard pipe thread adapter, 'likely' a 1/2" one.
Then the top heater hose (top of t-stat housing)loops over and goes to
the front of the manifold and continues on out the back of the manifold
and up over the valve cover to the heater core at the firewall.
Even with the warm water in the manifold or in the carb base, sucking
fresh cold air will cause ice problems. As the air speeds up going down
the venturi, it condenses and causes ice.
That is the big issue with that 'off road only' air filter you are
using. It has no place to suck hot air like a street legal air filter
has. I have had those freeze on several occasions. Forget 'several',
change that to 'tons of'.
Nothing like having the rpm stay at 3000 and opening the hood to find a
block of ice where the carb should be.
A proper air filter has a vacuum and thermostat operated bypass that
sucks warm air from the exhaust pipes until the air inside the air
filter is actually heated up. You can make an air shroud out of a chunk
of tin or sheet metal for the hot air intake on the header and just use
a couple muffler clamps to hold it on, but you need a proper air filter
to use it.

roading?
