Penta crank is from marine engine, you should note that there are few different blocks, B23 is older type, then there are B230 older and B230 newer, difference was with main bearings so crank need to be for appropriate engine version. Also at least in finland Penta cranks are about 1000 euros.
Marine engines begin with AQ code, something like AQ171.
I think you could go with B230F, it is injection engine with electrical fuel injection and you would need to swap oil pan and oil pickup from your current motor + engine mounts. Oh yes, if it had distributor at back of engine it won't fit to 360 without cuttin heater box or relocating distributor to engine block, there should be place in block, if one is lucky there is also needed gear in auxiliary shaft, but of course you could swap auxiliary shaft too.
Not sure about starter, that might be different and alternator could be on wrong side causing some work with wiring or then relocation of alternator, not sure if some threads need to be made.
Waterpump is also something you need to switch over from 360, I believe.
So it is 'straight' swap, needs some work, nothing impossible though and would provide nicer drive.
With B23 there are some differences in parts so it could be you would need to source 360 B19 to switch them, however I'm not 100% sure if that is really needed as I don't remember what exact parts were different
