Help evaluating this car...69 DART

My whole point is as op stated he already has the LS motor and apparently likes the Dart Body Style. Another Point..Yes this is " For A-Bodies only " But is says nothing about having to be a purist to participate. How about we answer his basic question which is " Is the car worth $2500 ?" instead of ripping him for drive train choice. I could understand if it was going to be a restoration but it's going to be a Drag Car. Who gives a rats *** what engine is in it as long as it's fast. I know I'm in the minority here but that's nothing new. :)

Just want to clarify something,.... My comment of "This IS ForAbodiesonly" wasn't directed towards the original poster. It was to the person that made the comment about people being "Elitist Snobs". My point was that commenters weren't being snobs, they just didn't want to see someone put an LS motor in a Dart, which shouldn't be surprising considering it is a sight comprised of people who like A-body Mopars.

I saw numerous people offer suggestions for other options, as well as saying they agree the LS is a good foundation and cheap to build good power. I'm just saying if you are going to come into an A-body fan site and talk about cutting apart a clean A-body and drop in a Chevy drivetrain, you might expect the purists to suggest dropping the LS into a different car, or go another Mopar option.

Let's not forget that the original post said:
Hi, I'm a newbie here and looking for help on what you guys think the value of this car would be as is and for ideas on building.
POWERTRAIN:
Don't scream brand loyalty, but I have a 416 cid 13.5:1 LS3 engine that makes around 650rwhp and would mate it to a TH400, custom driveshaft to a rear end which would be undecided. I have reasonable fab skills, can weld, will be doing most of the work myself.
I have no problem w/a 440 (use to have one long ago in late 70s), but I would wonder what it might cost to build one today.

That tells me the OP was not completely set on the LS, and was open to hearing other options!
