1971 Plymouth Duster Specs

All updates on my Duster can now be
found in our tech forums, MoparTech.net!

GOTCHA ! !

   Well, here it is folks.  The finished product.  Just over a year in construction (minus engine/tranny) and it's finally done.  You can see pictures of it on my '71 Duster Gallery pages.  I also finished up the 416ci stroker with the Mopar Performance 4" stroker crank.  At the end of this page is a list of the things that I will be putting together to convert it to a W2 stroker

This list is the current driveline installed in my '71 Duster.
Recent changes or additions are listed in GREEN.
