stroking with a 360 crank is not very cost effective considering the cost of a full 360 would be cheaper and yield mor inches.this may not be true however if you are a machinist?stroker kits for the sbm are around 1300 with excellent rods,forged pistons ect and yield @ 390 inches with a 318.

it sounds like you are somewhat new to mopars.ill give you some great advice.build whatever motor you have with whatever parts you have.all mopar engines run great and that includes a 318.there are combinations of parts that are better,but there is no bad way to put one together.enjoy whatever stuff you have and dont fret alot over trying to find a certain set of heads or intake.let me know what you have,what you are trying to do, and the budget in mind and ill give you some ideas.
