I will add it depends on what character you want the car to have.

The gen 3 hemi can make the power NA. The heads have the flow potential and the block can take it. You just have to spin it up... torque is limited by displacement.

The BB stroker can have lots of mid range torque aided by higher displacement. It may feel stronger in normal driving.

Turbo or supercharger options on either one can increase both torque and power. I do not think these are budget options however. Also there may be trial and error involved (eg. trashed long block) which can increase cost significantly.
