360 Married to A833?

Hi Mark, I didn't realize Scalloped referred tight pressure plate mounting – learned something new today. The original clutch on the 273 Commando Barracuda was also built that way to increase clutch plate surface area but no one ever referred to it as a scalloped clutch.

However, I assure you the 10.875" setup I am currently using on my 10.5" flywheel required considerable more pedal pressure. It actually broke a factory welds on the Z Bar, on one of my early outings. I have also braced the fire wall to the shock tower. I almost gave up on using it because it was so difficult to adapt but it cost a small fortune, so I kept at it.
