273 and 318 the same block?

Interesting idea..........now here's one to chew on Call up Darton Sleeves, see if they could come up with a max bore sleeve kit similar to what they have for the 3rd gen Hemi then ANY LA block could go out to max bore......and with a good poker face, say it's just a good running 273, 318.....show them the casting number on the side of the block for proof.
