Is building a stroked 318 better than a stroked 340/360?

So I was planning to put a 440 in my 73’ Duster and decided to sell off all my small block stuff and did so over the weekend. At the same time, I was offered a deal on a torquestorm supercharger for a small block and think it might be a fun little combo for the duster instead of the RB engine I’m building. Now all I have left are a couple early 318 engines. Thinking cheap fun might be the way to go for now, contemplating building a 318 for the little huffer and running it in there.

So my question is, what benifits to stroking a 318 than a 340 or 360? Mind you, I’m just talking short blocks here, nothing to do with heads or intakes, just block wise. Now I know some 340’s came with forged cranks, but I don’t think anything really different between the LA blocks. So I’m asking if there is any difference between blocks strength and is it feasible? I could spend another $600-$1000 for a 340 block, $500+ for 360 or use that money towards the 318.
Like to hear some opinions on this.

Using a blower is going to fill the cylinders. Yes more cubes = more torque, but you need to get a block. I would just build the 318 block. Yes you may get some valve shrouding but the blower works past that to a point. With a blower the need for large intake valves is negated, but bigger exhaust valves will aid breathing, along with porting. Use the cost of a block towards valves, exhaust porting and valve springs.
