Which small block A Body is the most sought after

Tarr said
That the 68/69's are the hottest. The Cuda brings more money but The Dart is close behind. The problem is you NEVER SEE 68/69 CUDA'S for sale. People that have them don't sell them on the open market. I can only assume that if they sell, they do it on some private market. Other than that the 68/69 Darts bring the most money witch tells me that they are the most favored. I have a 69
Dart and am tickled. Eat your hearts out. I will be even more impressed if I ever get mine back from the body shop.

I think you are right about the non factory 340 and 383 cars. The 318/273/slant 6 Barracudas bring more money easily in the compared to a same condition Dart.

But selling prices for 68/69 "S" car seem close to GTS and 340 Swingers.

I know a extremely nice 383 4spd 68 Barracuda Coupe brought around $35K on ebay recently. A similar 340 car will not sell for more. I think a 68 383 4spd GTS would be similar or more. Even though the coupe is rarer than a fastback, the coupe will sell for less money.
