Since the bore and stroke of the 340 seems to be the magic number, has anybody used a 360 block and destroked the 3 5/8 to a 3.31 stroke like the 340. I know it would be a custom crank because of the bearings, but look how many more 340's there could be. I had one back in 71 in a Duster and that baby ran great.

Have you ever spoke to Kevin @ SK speed. He loves the 340 and thinks very highly of it.

IDK if you could destroke a 360 crank to a 3.31 throw.
Is it possible?
Hughes engines has a thing (that I’m sure someone else makes and be purchased cheaper) that would allow a small journal crank to be dropped in the large journal 360. It’s pricey but if it is the bore and stroke combo your looking for……
