318 stroker using Scat crank

I don't understand stroker 318 the only reason I'll would build a 318 is cause I would want a short stroke engine the 318 is a poor man's 340. I wish they made a 3.31 crank for 360 blocks. When building a stroker the only factory part your using is the block and a 318 bore size ain't bad, but I'd try to fine a reasonable price 340 block but settle for a 360 block. Even with 3.58 stroke that's what my cousin run 340 block with 3.58 crank.
