Another piston option for the 273.

G’day I’m another Aussie,just found this thread,coz funny enough,I’m doing the same thing.Holden 253 pistons on a 3.58 crank,standard bushed rods, if you buy the pistons with 1.70 height,you get ‘013 out of the deck, that’s ok.
This is a retirement build to replace my W2/410 combo in my yellow car,and let the wife drive it.
