Greetings! I'm a new member with a newly acquired '60 Dart 2D HT with what i think is a 318 poly. Looking for tips, advice, hi-po stuff, etc. Any help is appreciated. Any other owners out there?

 

That's a fairly rare find you have there. Haven't seen many of those, post some pics when you have a chance. Not a lot of aftermarket support for the poly engines anymore- best bet is to score some finds at a swap meet. Check out some of the specialty vendors in MCG or Hemmings as well- might find something there.
