67 Dart 270...Project Old School
With all the rain we have been having I got some time to finally finish up the cold air induction setup for my 67 Dart. When I cleaned up the 360 engine 3 years ago I installed a Spectre Performance chrome air cleaner with two air inlets.
Now I needed to figure out where to draw some cool air. I finally settled on the radiator support, but it is very crowded. On the driver's side the battery sits so high it prevents getting a straight shot at the radiator support. Several years ago I pulled the factory battery tray and shortened it about three inches and welded it back together. I was using a physically smaller battery which allowed me to move the tray down to the frame rail. On the passenger side, the horns and relay are in the way. In my last bout of cleaning up the wiring under the hood I moved the horn wiring to the drivers side fender. I plan to mount the relay and horns on the frame rail under the battery tray.
On Saturday I picked up a exhaust adapter that is designed to connect two 4" diameter exhaust pipes together. The overall length was 8". I also went to Lowes and picked up a 4 1/8" hole saw.
I cut the exhaust adapter in half and then cut off the sloted slip fit portion. What I ended up with were two pieces of pipe with 4" OD on one end and 4 1/8 OD on the other end. The hardest part was trying to find a place on the radiator support to cut the holes that had a flat spot for the center drill bit. Cutting holes on non-flat surfaces is always scary, so don't forget to wear some gloves and eye protection.
Test fitting the exhaust pipe adapter in the hole:
I tack welded the pipes in place. The metal is so thin and my crappy welder wants to burn holes in the radiator support, so I just tacked it in four spots. Be careful and don't tack the pipe to the fender metal. You may want to remove the fender in the future.
This is what it looks like all mocked up:
After I tacked the pipes in place I used seal sealer inside and out to seal the hole around the pipe. Final touch was some high temperature black paint.
