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

mikeyt2014, I don't think it is possible to get 10.3:1 compression. If you follow toolmanmike's build thread (link is in his signature line) and look at post 169 on page 7 he ended up with 9.6:1 using the "high compression" Egge replacement pistons with a little shaving on the heads.
