I came across a very odd situation where I have two 2.5 liter cams and two 3 liter cams. The two 2.5 cams are the 1999 SVT cams and 1998 SE cams now these two intake lobes had a lift of .19 on the cams which were the same for the two cams. The 2.5 cams have over 100k miles on each one where the 3 liter cams are less then 60k. The two 3 liter cams which are one 2001 escape cams and the other 2001 taurus where the two cams intake lobes measured a .17" lift. Now the part numbers are all the same as far as the replacements but we all know ford will make all the cams on the shelf the same to save inventory. Now I posted a video on NECO which was proving to Buckeye that the measurements I made were right. So did ford change the cams in 2004 and just made all the older ones the same part number to get them standardized. Now the service bulletin shows that the new 2004 is the same lift as SVT and SE which was verfied by Buckeye too. He also resourced back to the 2002 on his bullentin to see the lift on the cams and they say 2002 should also be .19" . Now I want to rule out th efact that a 50k motor roller cams not even pushrod style will wear that fast with low miles.

I need someone to make the measurements on the lobe be sure to zero out first then see what lift you have. List the year and engine.
Second his bulletin all saids the Rocker arm ratio changed 2004 to a 2:1 where before it was 1:8 now I did call Bill Jenkins to see if the heads were the same because in order to gain a bigger ratio you must have a longer arm right? Or I am missing something here. But to cover all my unanswered questions I also asked him to see if the valve lifters, cams, valves. roller finger were any difference in part numbers. "Bill said all the same from 2000-2005" what are we missing here nothings adds up I think either Ford is being lazy here or what?
Any info would help because maybe the 2004 engine will be a better setup with the higher ratio if the heads are different. I also want to get more info on the cams so we can make the best full swap. I am thinking if the earlier 3 liter have lower lifts then the best swaps maybe full 3 liter swaps 2004 or earlier swaps using the SE or SVT cams for better lift. Or even better than all the SVT or SE cams may make the 2004 a really around great motor. joey
