273 question

I shoulda added this at the beginning..I have to get new heads, both are cracked, #! crank journal has a ding on it somehow. #2 cylinder has a small rust pocket, so I was just going to have it sleeved and bore the others. The shop has another 273 to buy that I was going to cannibalize, but wow costs are crazy.

Scrap that 273, keep the rocker shafts, timing cover and timing tab, and the oil pan and pickup. How much do they want for their 273? I am partial to 273's but I won't sleeve a block. At this point, any small block will do. 273 or 318 will work, depending on cost. Not sure about a magnum as I have not done one yet.
