i have built A bodies w/new .870 ( stock 340) bars and thought they were a bit "oozy" but adequate.
Then i built a Dart with .890 bars and really didn't see much change.The .920 were nos from Mopar way back when and actually mic'd close to .940 but there never was a .940?? so i assumed they were .920's?
The bilsteins i took off came from Firm Feel and have the same stroke as stock B body shocks so i wonder how they would perform on a heavier B body?
But as you say ride is so subjective and what is acceptable to one person may be too stiff for another.
