Restore or Restomod

Taking a poll
I have a 1969 Dodge Dart GT, 273 Torqueflite, Console, Buckets, A/C.
According to E-Booger, it is one of 4,976 made. I got it from the original owner, parked since '89. Have all the original stuff including two window stickers, lot tags, etc.
It has like 180K, but is a Valley car with no rust at all other than surface on the top, hood and deck lid. It needs a complete restore, but is a solid car to start with.

I don't want a rare car again, had a 1968 Hemi Road Runner back in the 80's and it stressed me out all the time because I was afraid I was going to break the original engine.

I don't think a 273ci Dart GT will ever be a hot commodity, but I don't intend on getting rid of the original stuff.

Here is the question:
1 Restore numbers matching
2 Restore, but stick in a 440 and 4 speed (which I have), M code tribute but with upgrades.
3 Restomod with 440 or 5.7l Hemi (also have)

I need a plan.
