LS3 and TR6060 swap advice

[cc-rider]

Has anyone swapped a LS3 engine and TR6060 tranny combo into a C10? I've got a 67 C10 that I'd like to try this on. I'm having a forged motor built for my 2010 Camaro and I want to put the stock LS3 from that into the C10.

Are there any major fitment issues? For instance, does the cab tunnel need to substantially modified to fit the TR6060? I know motor mounts will be needed. And likely some custom work too. Not expecting it to be a drop in. Just looking to see if anyone has done this particular swap and has some learnings to share.
