I want to get it to running its best and then figure out what to do from there
Note there is nothing such as a 270 Slant-6. "270" is the model series of your Dart. The 170 was the basic/low-trim series. The 270 was the high-trim series. The GT was the premium series. It's a little confusing because the standard-equipment engine was a 170 cubic inch Slant-6, but any Dart model could be had with any of the available engines. Your engine is either a 170 or a 225 Slant-6. Look at the driver's side of the engine block, below/behind the manifolds. What casting numbers do you see?
