4.00" bore
3.00" stroke

Stock heads are 64cc, .041" thick headgasket, and stock pistons are -5 cubic centimeters.

How far is your piston down or up from the deck? It can vary from -.010" to .010" or so.

Using .005" below the deck and a 4.100" bore diameter gasket, I get 8.830:1

Compression Ratio = (Clearance Volume + Displacement Volume) / Clearance Volume

Clearance Volume = Combustion Chamber Volume + Piston Dish Volume + Deck Clearance Volume + Head Gasket Volume + Volume Above Compression Ring

Displacement Volume = (pi/4)*(B^2)*S
