| I am intrigued by your numbers at 17 psi with the mod list you have. On pump gas the only way to make those numbers with your mod list is to raise timing to ridiculous levels and ride the knock sensor :). I find it amusing that you want to "build" your motor. Please feel free to list the following specs for your short block build. 1. What stone will your machine shop use for the final hone ?2. Piston to cly wall clearance
 3. Ring gaps
 that will be more than enough  Harry
