It will be in the 100 pound range. To many variables to give sure fired answer. To bring the compression up to a larger degree you will need to make the firing chamber smaller. You can get there in two ways or both. You can get .200 off the head and use a domed piston to enter the firing chamber.

The only domed pistons you will find for this engine will have to be a special order from the hot rod custom piston manufactures or having a machine shop TIG and machine them to fit your application. Both are costly. I did my own having a tool shop with the equipment.
