Either will work just fine it you change to a powerglide you will need a new (longer) driveshaft. But since the glide has a higher first gear ratio it should be more consistent. But it may be a little slower and you will need a good planetary to make it as reliable as the 400.
I'll see what my machinest has laying around. You might consider a GM crate 454 or 502 or if your budget permits a 572.
