The final measurement of the short-block is the deck height, or where the top of the piston sits in relation to the top of the block deck at top dead center. Our engine ranged from .026- to .027-inch deck height. Combined with a .034-inch head gasket (when compressed) and 64cc chamber heads, our 427 will net out at exactly 11.2:1 compression. With aluminum cylinder heads and a pretty radical cam profile, that will run on pump gas just fine.
