your block was for sale in 1994 hemmings cast no# 3932386 cast date of J-15-8 suffix no# V1019DZ IN ohio ken no# 216-666-6699
Something does not add up. No "486481" in 1969 or 1968 model years. ???
With that date I would say it's 586481. It misses my car by 66 units which is an 01C.
Pretty close to mine, too. That assembly date is pretty far out for an 01C car, though.
9N586481 looks pretty good for that engine date.
