340 or 360?

I think the Op is 340, or 360 why?

The 340 is the premium small block and always will be!

The 360 like the 400, it is a truck motor with a cast crank...

But if the OP wants specific usage for cost involved then it will change the argument...

We can say 318-LA or Poly 318...
Also 383 hipo against 400 etc.
426 max-wedge against a 440, the list is endless.
