Timing Chain Tensioner 318/360

I have a rather unpopular opinion on that item, so flame away.

It is nice and all, and was made for 3.9 v6 because of the inherent problems with that motor. It was not designed as a v6, it was a quick solution to the lack of a v6 in the line, by dropping two cylinders from the LA motor. The 3.9 had more harmonics and vibrations than the Supremes.

But if you look how a timing chain works, one side is a tension side (cam drag/pull loads the crank) and the slack side (chain returning from crank to cam).
In my opinion there should be no cam timing variation that is worth the added friction from the chain tensioner on properly built LA motor.

I may be wrong, but that is how I feel on the subject.
