Response to Anyone have forged standard pistons?
What would the compression ratio of this piston?
It's stock bore/stock stroke......
1.290 compression height
I came up with 10.8-11.5..... Just trying to decide if these will work for my pump gas build? I will throw in about a gallon or 2 of 107 oct....
Have closed chambered heads.... So around 64-67cc heads.
