Grant,

Yes, they can be spun that high or even higher if you have the right clutch assembly.
Although you don't mention the brand, I would suggest you talk to Rob at Advance Clutches or the guys at Ram Clutches.

Yes. 10,500 consistently in an SS/DM. We tried other "trick" clutches, but ran our best with a single disc soft loc.

I used to leave at over 10,000 and crossed the finishline at 9400 with a McLeod 10.5" unit and an alum flywheel. I don't use a Mcleod anymore but didn't have any issues from an RPM standpoint when I did. I would highly recommend something smaller diameter and dual disc from a performance standpoint if you are starting from scratch.

thank you for the reply guys.i am putting my 400 ci comp engine in my fairlane for fun this winter.i could use my liberty and dual 7 east west deal,but wanted to keep it simple and run what was in there.a 5 spd lenco and a soft lok clutch(mcleod).just wasnt sure about the rpm,simply because the current engine only turns 8200,not 10,000 plus.grant.
