340 A Body Torsion Bars

Yes, they are .870". We have run them with a 383 in a '67 Barracuda. That car was loaded, too. It had AC and power steering. With the stock 340 sway bar it drove fine. It wouldn't corner like my son's '67, but it was fine. Both my younger son's Dart convertible and my Barracuda convertible have stock big block torsion bars (.890") and sway bar. Again, they drive fine and handle reasonably well. Both cars have 440s.
