Not familiar with the 61-64 engine swaps; as with the 65-66, converting to a V8 is usually not as labor intensive. Ran a cursory search and came up with a couple of links on the subject, may want to run another search and suggest narrow field to the 61-66 forum. Likely a more knowledgeable member with the swap will be able to provide more info, again welcome to FTE.

Installing a SBC in a slick is gonna make it absolutely worthless. You will never be able to sell the thing. About the same as buying a diamond ring and powdercoating it black. Just doesn't make any sense.
