Need some Drivetrain advice on a 53 3100

[Big J]

I'm trying to help out my buddies dad. He has a very nice original restored 53 3100. It has a 235ci 6cyl 3spd on the column. He want to change over to a small block with a 3 speed manual tranny and different rearend. Does anyone have a kind of a parts list laying around or a build like this to point me in the right direction? Radiator, motor mounts, tranny, drive shaft, rearend? Looking for this to be a bolt in application with little fab work or is there more to it? Thanks in advance.
