Are 340’s rare

How rare are 340’s getting now days? Pulled this solid runner cast crank one out with 727. Not sure to keep it stored or sell.

There’s a lot you can do to freshen up that 340. Go back to stock or get crazy n do a 416 CI Stroker.
I’ve alway heard n I had a 360 Stroked to a 408. Lots of low end torque. Google 340 Stroker kit n read up on them.
