The Stovebolt Site Forums The Shop Area Engine Shop Consideration for 216 for 261 swap?

What should I consider while preparing for swapping my 216 for a 261 in my '52 Burb? What I've come up with so far is:

-Water pump adapter plate
-It has a 12v generator so new regulator
-Bellhousing? Do I use the 216's?
-flywheel?
-Clutch?
-Accelerator modification?

I'm sure there are others but this is what I've come up with so far.

Thanks
