help with what 350 I bought

[yenkoman]

I bought a 350 because it had camelhump(fuelie) heads for $300 and knew it was rebuilt from another owner that moved away.cast date E269 is that 05/26/69,block V0529WK does Wk mean suffix 69 350.Block casting#3970010 shows me it should be from 69 z28,LM1 or SS=L48 from the definitive camaro book,am I right or no.The heads have me stumped #3782461 and date B263 and the other head is C52.No holes drilled for brackets.It Has a 8" harmonic ballancer,doubt its a offset keyway though.I want to start another 69 camaro project so this might be the start.So if this is not a Lt1 engine,what is it exactly and what year are these fuelies.
