Interesting question. I can't really say, not having much contact with L6s smaller than a 292. I know the prior generation of Chevy L6s were sold in 215, 235 and 261 CI displacements. Heavier cast iron blocks, though. The next Generation, from 1963-87[?] ran 194, 230, 250 and 292. 230s were not used in trucks after '67.
I have heard of racers building "Cheater 292s" by using a 292 crank in a [1-7/8th inch lower] 250 block with oversize diameter pistons, for getting around racing class rules. I don't race so I only have heard of it in passing.
You might ask around at Inliners International. Someone there might know about it.
