First let’s discuss carburetion. The non-hemi engine will come with any one of three carburetors. SP, ruxing, huayi. The hemi engine only comes with the SP carburetor. All of the carburetors have .014 to .016 low and .028 to .031 high. Some of the carbs have a 140 e-tube and others have the clone tube. The only difference being the large hole in the 140 versus the small hole in the clone tube at the bottom. That tube and the entirety of the rest of the carburetor can be checked by all of the clone tools. As I stated earlier the center lines are all over the place anywhere from 105 to 118. I have seen lift on the intake as low as .208 and as high as .224. Duration is not always the same but relatively close from one cam to the next. At the .050 206 duration is the most I have seen. When compared to the clone of 214/221 you can see it is not close at all. Same at the .200 check. Predator around 73 degrees where the clone is allowed to be 81/88. I am soon to do a new video comparing the non hemi to the hemi.
