5.3 swap into 72 C-10 Part list.

[WB72]

So i have searched the threads, but didn't get all the answers I needed. Can you help me??

I have a 5.3 /4l60E to replace a inline 6 250 / 3 speed Manual on another project.

Correct me if I am wrong:
-I will need to use V8 motor mounts before I use the LS adapter plates.

-is it better to move the engine more forward to have clearance at the firewall? or will there be clutch fan issues if using factory fan?

-will 73 up motor mounts work better for this application?

-will I need to replace the oil pan with a smaller one? i will be planning on lowering this truck quite low, I do not want it to be damaged.

-are there any headers that fit nicely in between the frame rails/ motor mounts?

-A new transmission cross member will be needed.

-I have the donor trucks crossmember, although it is for a 4X4, which I will not be using since i will have a 2WD. would it make sense to modify that to fit or build from scratch or is there another possibility?
