Got my 408 stroker in the car, fired it up and runs like a bat out of hell! The only problem is when I start to cruse around 50mph it starts to miss. I checked all the new plugs and wires, everything is in order on that part. I am running rich with the new injectors 42lbs and the trex cam, the injectors have already been tuned down around the 5.65 up too 6( flow rate). Could this be my problem for missing and running too rich. Think my brand new plugs may be bad after 200+ miles? Any input would be great. Thanks Chris
