Real McCoy,
Caveat Emptor!
The first Powerglide 235 wasn't till '53!
The '50-'52 Powerslide('scuse me!) were 216s w/hydraulic lifters, and more importantly, had the smaller throttle body that does NOT fit a 235 manifold and has smaller jets too.
The price sounds high, and I'd be sure that it'll fit your manifold first!
I learned about the difference between 216 & 235 Rochesters from a $5 flea-market carb- squeaky clean, but too small for my '54!
(I did hang on to it though, and 15 years later owned a '50 Chevy Fleetline with a 216, and finally used the carb on that!)
