1st Ls Swap 72K10 Ly6/T56

[RB72]

My name is Ryan Burks and I am 20 years old. I am just starting my first build on my first vehicle I bought. 72 Cheyenne K10. I believe I have found the motor I want which is a 2009 Ly6 out of a 3500hd so VVT only. My truck is originally a 4 on the floor and I want to keep the manual transmission. However I have a few questions when it comes to that...

Why do you not see many posts about these swaps with manual transmissions? I know they’ve been done, but info seems to be a lot more limited on them rather than automatic trans. I’m wanting to put a T56 in it and was wondering what all I’ll need for the T56 to connect to my motor and transfer case. Any other problems that may occur along the way I should be warned about? Thanks! Any help is appreciated!
