Default SBC vs LS1 clutch compatibility

quick question:

Will a SBC pressure plate bolt up to a LS1 flywheel? Is the bolt pattern different?

The 10.5" clutch disc compatible pressure plates are different bolt pattern than an LS_ pp blt pattern.
I've never compared the larger clutch pp's to the LS_ pp's.

The bolt pattern for the stock 11" SBC plate will match the LS1 flywheel. There may be a difference in dowel-pins location and or presence but that can be taken care of easily. Check your stack height and bearing depth as well to insure that you have the proper geometry.

I had the same question. I do remember the Centerforce pressure plate I used had multiple holes for mounting. I want to use it if I can for my LS swap. It would save me a few $$s/
