What COP's?

What year is your truck?I believe the 3v engines came out in 2005,and the 4v(32 valve) are in Mustangs and Cobras.If your truck is manufactured before 2005,its more than likely a 2v.Hope this helped,from what I've read on the Moto blue cop's they are an excellent choice,good luck.
Actually, 2004 was the first year of 3v heads, but that is in the new style trucks. However, 2004 also had the older style "Heritage" that had the 2v still. The 4v was a Navigator engine, as well as the mustang cobra's, mach 1's, Mercury Marauder etc. In any case, just tell us the year and you'll be set.
