273 time to 'fish or cut bait'...

All 64-67 273's had solid lifters and adjustable rockers.

This is where I admit I get confused... my '65 FSM shows an illustration of the 273 rockers and they are stamped..... that is why I have to wonder if the heads/rockers have been swapped at some point. A lot of this has gone on and with the changed manifold, who know what you have?

OP, if you continue with the 273, knowing what heads you have is needed to plan out the right pistons. So get that casting PN and we can all work with better info on what you have. OK on the rationale on the heads begin worked on. If you want a 'standard' engine and then a 'hot rod' engine, that makes sense as long as the money lasts LOL

And I disagree with the idea of using 2 BBL 273 pitons; the EGGE 4 BBL pistons will barely get you to a true 9:1 static CR with the right heads. The 2 BBL pistons will actually end up at a 8:1 or less. The OP wants lots of good torque for his use... .which points to higher CR and more cubes.
