Borg and Beck vs Diaphram

This may be a silly question but on summit a RAM automotive flywheel for my 340 is saying the application is for a Borg and Beck style clutch.... now I didnt think that it mattered which style clutch it was for the flywheel because the clutch disk/friction disk itself it whats touching the flywheel. Was I mistaken?

From my experience, no. IMO the B & B clutch is easier to drive smoothly. Most Long clutches have tended to be on/off deals making smooth starts at low rpm difficult.

FWIW: Back in the day, manufacturers used to put Long style clutches in press fleet cars so they would live under the balloon feet of the scribes driving them. The press, in turn, would ***** about the rough or tricky clutch engagement. Invariably, they'd ***** about clutch slippage on a B & B car unless they got to it early in its life in the press fleet.
