my 292 block is decked .030 on my daily driver...I use the full dish piston...head is milled .090....cam lift is .520....I could have gone more...mine is not zero decked....
anyone else have a decked 292 ?

the math worked out to approximately 9.3 CR...if I had decked more AND milled top off piston i could had gotten over 10:1 and still have a strong block deck and piston..ever see how much "extra" material there is on the 292 full dish piston?
this is why i suggest using the full dish piston..by cutting top and bottom you can 1) lighten piston and 2) deck block MORE than zero decking and cut off top of piston.....since top of full dish piston is just a ring/circle ,its ok to do and these pistons are VERY thick in that area- I have had this checked with an race engine builder-he says standard procedure for him......
