was a 350ci small block a standard engine in 1969 corvettes?

There were two options for 69 corvette with 350 The base Engine was 300hp @ 4800rpm / 380 torque @ 3200rpm The optional L46 350 was 350hp @ 5800 rpm / 380 torque @ 3600rpm

1969 Was the first year for the 350 small block in the Corvette. There also exist 2 427-cid engined cars, or at least, two were produced.

Yes there was actually four options for the big block that year L36,L68,L71 & L88. They ranged from 390HP to as high as 450hp for the L88 which was far unrated, more like 550.

littlehorn is wrong. 1968 was the first 350
