They tend to feel more like a new clutch for longer. Overall quieter and more well-mannered if that makes sense. Interestingly the T5 I got (from an Astro Van) was mated with the 11 inch clutch if the larger passenger capacity option package was chosen. So an 11 inch disc wasn't all that hard to find.
I have been thinking about the SBC flywheel and I think I was told the center section (where it mounts to the crankshaft) wasn't the same size as the 235. Jerry (HRL) would know and might even have one he could look at for comparison. I don't think it was smaller than the 235, however. I think it was larger.
Been considering the Astro 14 spline clutch for my T5 swap. Would I have to have the 11 inch - 235 flywheel to make that work?
