You do know that when changing to the svt cams, you use the SVT timing parts.....and timing chain....including the timing sproket on the crank......Atleast thats what we did becuase we were worried about the same problem....and i ahve heard of people jumping teeth with in the chain because of it.
That was my understanding form Terry Haines too....that when using the bigger sproket SVT cams, that we should trnasfer ALL of the SVT timing parts to make up for the sproket sizes diffrence..Also the 2.5 liter chain (on most, some are actually smaller) is thincker.
