Had a couple miniutes to go look at some other late 60's big blocks i have including the 69 L78 Chevelle i have in storage and this is what i found.The 3's were rounded on top,the 7's back was bent,the 4's were closed and the 1's didnt have a foot just like the the stamping on the block in discussion.
It looks right to me!I didnt buy this engine because i needed it,i bought for what it is and hated to see it get torn up in a race car.
