Resurrected Junk
When you see the PowerPipe in the previous post, it's easy to see what it does not have. What I hadn't figured on was what ALL that meant.
No intake manifold heat. Anyone installing a PowerPipe or a header will have the same issues with a stock intake. There is a version of the Dutra Duals what retains the manifold heat feature.
1. There is now a hole in the bottom of the intake under the carb that is the port for the EGR.
2. Going past the hot pocket in the top of the exhaust manifold there are two lugs that the throttle and kickdown linkage bracket is mounted to.
Solutions:
1. I used the smallest oil galley plug I could find to drive into the hole in the intake to cover the EGR hole. Even so, it was a little large requiring the hole to be enlarged for the plug to fit.
2. 2 pieces of 3/8" ID steel pipe cut 5/8" long were installed to take up the space formerly taken by the exhaust manifold lugs. Another approach would be to bolt the linkage bracket to the bottom of the intake and adjust the linkage lengths.
No choke pocket. Haven't seen any non-Mopar manifold that retains this feature. Here at the Edge of the World, a functional choke is helpful for the first few miles when the temperature dips below 40° F. The choke is held in by one screw that also holds down the throttle return spring bracket.
Solution:
Using a 1 7/8" (stock exhaust) pipe clamp and a lever fabricated from sheet metal, I provided a screw hole over a PowerPipe tube to attach the choke spring and assist. The lever was also notched providing a solid attachment for the throttle return spring. The choke rod needs to be shortened about a half inch as does the throttle if you want to maintain the same pedal pressure. I shortend the choke rod by putting a kink in it. I left throttle spring alone which decreased the effort on the go pedal a little.
It was also necessary to bend the sheet metal on the choke a little to allow it to settle in its new home in relation to the intake manifold. The sheet metal on the choke also needed a little cut to allow it to fit over the lever near where the attaching screw is located.
Here's the pix to help with the visualization thing. I guess I should have taken some photos of the completed assembly. If there are questions, I'm glad to take and post.
