273 Engine set up I'm thinking of going with, let me know what you think

Yep ^^^^^^^^^^^^^^

Look into Egge pistons for your 273.

I like your other thoughts.......I'm guessing 240/250hp depending on your final compression and how good the valve job is? Keep in mind that the factory numbers were "gross" ratings. I'm talking more of a net rating with my guess.
