Finally a way to get more out of your 440 without swapping engines. Using Carl's new 660 cylinders, no bottom end modification is required. Kit includes ported cylinders, modified head and valves, new piston kits, all necessary gaskets, cylinder studs and y-pipe.

Note: Stock 440 carbs and exhaust will not work with this kit.

For even more performance upgrade to case porting for only $150.00.
