273 or NOT 273?

Believe me , I want to build one just to say , Yeah , It's "only" a 273 , but I think the cost would be a lot more than a 340.

Could always find a decent 273 short block milling and notch the block add lapped magnum heads, cam her up and see what she'll do, if you like the results then think of a full build.
Kind of what I think I want to try.
