I was thinking to myself that if the crankshaft on a stroker motor is smaller therefore creating a bigger combustion chamber wouldn't the compression ration be a smaller number or what? How do the guys with the 422's achieve a compression of something like 11.2:1? thanx alot.

Since my 5.3L heads have 56.8cc chambers I went with -19cc dish pistons to get 11.18 compression. A stroker motor increases the stroke of the crank. Custom pistons are required which can be made to get whatever compression you want after a head gasket has been choosen.
