440 duster

If your Duster is a V8 car 73 or newer all you need are late model spool mounts and make your own DC K frame. Info is at Bigblockdart.com
Years ago I started my project and couldnt afford the K frame, I had a 75 fury with a 360 I was junking so I cut off the spool type K frame tabs. Used the new mounts with the tabs hanging down to locate mine. The trans mount will give you the correct for/aft position. Mark the center position of the current engine and match it up. They are offset to the right side. The heigth of the crank is listed at Schumakers website. This is by far the cheapest way,buy the spool mounts used and replace the rubber with poly inserts. Earlier cars can be fitted with the later K frame but sway bars are different so get that too if needed. Smallblock torsion bars might work if you dont corner too fast. 6 cyl bars ok for Drag race use.
