Well, when you get to it ... if you're not already on LS1tech, you should get on there. In particular, lookup 69rsss and check out his very lengthy build thread, he's covered the entire 67-69 swap in explicit detail, and I think you will find some INCREDIBLY useful pointers from him. There are (of course) at least two dozen others who can claim the same, but I found his thread to be much more thorough than everyone else's and put into terms (with part numbers, etc.) that everyone could easily understand.

And good luck - I envy you. There is a guy here in north GA (Marietta?) that was posting on LS1tech recently that used the ATS mounts in his 67-79 F-body and he wouldn't shutup about how perfectly they put the engine in place.
