Identifying small block chev with engine numbers

Hi all, a mate has a 70's nissan patrol, Motor is apprantly a 350 chev. Had a look on google ect... for info about engine numbers butt ill be honest and say im hopeless with them haha! anyways im hoping someone on here can translate the numbers i have. I got the numbers off the block behind the alternator (drivers side) numbers are as follow.

From the little info i have found its from a 69 pontiac gto but like said not 100% sure how true that is. My mate just wants to know if it's a 350 chev or not.

Any help appreciated, cheers ryan
