250Ci swap to a 355ci What needs to be changed

[Furno68C20]

I'm about to start removal of a i6 250 engine and swap for a sbc v8 355ci.

The truck is a 67 3 on tree.

My question is what can be used and what cant be used? Radiator? clutch? flywheel? pressure plate? starter? ect....

Need to make a part list to order for the job to run as planned.

for now going to use the 3 speed that in there until i find a 4 speed saginaw or t10.
