Title says it all. I had a van I built a couple of years ago with a slant six and I put dutras on it. It was great. I traded the van for a motorcycle and stupidly did t pull them off. Now I have a 64 dart gt with a slant six, Clifford intake and exhaust manifold with a 4bbl carb. Everything is great other than I don't have a proper heat stove so it takes forever to warm up, and my exhaust manifold is super close to my steering column. So yes. That's my novel. Can I fit dutra duals with a Clifford intake or would I have to change to a stock intake manifold as well? |

You can fab up a hydronic hot spot under the carb at bottom of Clifford intake supplied with hot coolant from heater loop. I have a 195 degree thermostat installed. The one I made works quite well in conjunction with electric choke equipped 4160 390 cfm Holley carburetor governed by a coolant sensing thermistor made by Holley to slow electric choke opening, and Clifford headers. After a few seconds of feathering throttle after a cold start the car is drivable at any ambient temperature found in Maine… zero to nineties. |

He's using dutra duals, clifford does not have a spot like the offy manifold to mount the rear modified original manifold for dutra duals, and the original manifold heat stove with a block off plate will interfere with the intake manifold somewhat unless it's capped by some fabrication and welding instead of bolting on the block off plate...This manifold was originally supposed to go with their headers and the waterbox they sold, but they never thought about using a split manifold with it...The one I made works quite well in conjunction with electric choke equipped 4160 390 cfm Holley carburetor governed by a coolant sensing thermistor made by Holley to slow electric choke opening, and Clifford headers. After a few seconds of feathering throttle after a cold start the car is drivable at any ambient temperature found in Maine… zero to nineties. He can use the waterbox, if he goes with 'dual duals', or a small crossover pipe and plenum under the intake, but dual duals have another fun issue getting the rear pipe over the high mount starter. -D.Idiot |

I am running the Clifford 4300 manifold and a pair of Dutra exhaust manifolds. Everything fits fine. I am using a Ford water heated 4v base plate to provide manifold heat. You can find the base plate on FE engines of the mid '60s. They also show up on Ebay. |

There are two versions of the clifford intake - the later one (part# ended in WH I believe) had a water passage that stretched from one end of the plenum to the other with one 3/8 (or was it 1/2") NPT port on each end - meant to put hose barbs on there to plumb into the path of the heater core. This manifold will work with the dutra manifolds if you either grind the flange of the exhaust manifold (plenty of meat here) or the water galley on the intake (putting a hole in it making it un-useable) or some combination of each. The earlier clifford manifold doesn't have this galley underneath it so that won't be an issue (one shown in pics from wjajr). But as DI said - none will bolt to a stock exhaust manifold dutra-tized or not. |
