Camcraft also has cams for the poly.The cumbustion chamber is almost identical to the 2008 up 4.7L Chry V-8.The cyl heads can be ported to very close to the same numbers as an Edelbrock magnum with custom valves which are available.A friend is fabing an aluminum custom intake (single 4 bbl).Easy to stroke with available cranks.Overbore .060 easily more with sonic check.
