just dropped a 350 into my '88 cherokee-- trying to figure out exactly what year it is ---
driver side stampings are :

57L GSGI (right next to bellhousing)
GIIH

passenger side stampings are:
14093638

I've google'd this, and come up with everyting from an lt-1, to a 350 with no data--- any ideas what this motor put out in stokc form?
