Verifying for reference: Is the .920 considered a stock small block bar, and .960 a big block bar? Or is it more complicated than this?
small block bar is more like .860 or .870
my 67 coronet had the factory 318 bars in and i couldn't get the pass side very far off the bump stop after i put SS springs on the car.
i put some .960 bars on it and some bilstein shocks and the front is pretty dang firm now.
according to this, my bars should've been .880"

440/hemi bars are .920"
Improved handling is .960"
