First time build

Hello All,

This will be my first time build utilizing a recently acquired a 71 dart demon. It drives and runs with the slant 6, but I have a MOPAR 383 and 727 torqueflight that I would like to stroke out to a 489 and shove that in it. I realize this will be quite an undertaking and I look forward to all feedback/suggestions. I will keep posting as the progression continues.

Thank you all.
