1.88" Honda journals will get you a max 3.80" stroke. Not the 4.05"+ you would need for a 5.7 based 392. I might do this for a spare 6.1 block I have, which would be ~392. Prob $200-$300 to offset ground a crank.
>> These journals work in Hondas and NASCAR-only. 4340 billet crank is nothing like the oem hemi piece. 2.1" is working, will a sbc journal make it faster or more reliable ? You might want to peep the forced induction section, for MoPowar, ateam :(
