Correct torsion bar size smallblock vs bigblock

[sco440]

Are torsion bars from a small block the same size as a big block in 71/72 b-body? If they are the same size, what is a good upgrade for to use in a 440 car instead of the stock unit? Just a street car/driver.

FOR MY 71 SS-PLUS I ordered .960" diameter "B/RB" and Hemi handling along with the clips and boots from here for a good price ..

I just got my torsion bars from Marsh Performance ( mopartsracing.com). Went from a 318 to a 383 in a 68 Satellite. Went with .960" diameter. $188 for the pair. Received them in 2 days.
