  4. Predator 212cc Non-Hemi
There are two ways to know whether you have a Hemi or Non-Hemi Engine. Obviously the heads are different and this is easy to see by the valve cover of the engine. The Hemi will have a wide casted valve cover while the Non-Hemi is identical to the Stamped Tin Clone Valve cover. The other way of know is checking the part number which is 69730 for the Non-Hemi and 69727 for the EPA Non-Hemi. Even though these should be fool-proof way of checking your engine many of the parts are interchangeable with the Non-Hemi and 196cc Clone. Its important to know which engine and which parts are in you engine.
