Question on new clutch/flywheel sizes

[quicksilver]

Here's my scenario. I'm looking to get a new GM 350 crate motor for the truck. It's got a 3 speed tranny and I figured on changing the clutch out while I had it apart.

Summit says the OEM replacement for the clutch is 11", but looking at the GM flywheel (P/N 14085720) it says it's for a 10.4" clutch. If I get this flywheel will it work with the 11" clutch? I think it will, but I want to be sure.

It's got a 307 in it right now (installed by the 400 pulling previous owner), so worse comes to worse I could have the flywheel resurfaced and reuse it. I'd just rather have the comfort of having all new stuff.

Thanks for any responses.
