Dankjt -- You might want to ask (in the engines forum
)
if there is anything significantly different about the 235 blocks cast for the Powerglide tranny. I can't remember, but there might be. Otherwise, I wonder why they would bother to differentiate between Powerglide and non powerglide engines 
Could be an interesting bit of knowledge for all of us, as well as useful info about your own engine. I don't claim to know much, but what I have learned is that the info contained in the casting numbers, etc is significant and put there for a reason.

All Powerglide-equipped vehicles with 235 engines (1950 and later) used 235 engines with hydraulic lifters (except the 235-equipped 1953-55 Corvettes).
Hydraulic lifters in all Powerglide-equipped low-pressure 235s from 1950-1953, and high-pressure 235s from 1953 and later.
Mechanical lifters were used in all 216/235/261 truck engines: in low-pressure/high-pressure engines, except, maybe, in 1960 and later 235s in trucks equipped with the Powerglide transmission.
