You can change to a hemi K-frame and use hemi mounts or use Schumacher mounts or mounts from John Aruzza on your 440 K-frame. The 440 mounts won't work on a hemi unless you have the Mopar Performance block with the wedge ears cast in. If you have that block you would need special headers. Your 440 trans will bolt up to the hemi but you will need an 8 bolt flex plate and you can use parts like the water pump housing and water pump from the 440 on the hemi. If you have a power brake booster you may run into interference problems with the hemi valve covers. Where are you located in Washington? What year is the Cuda?
