oiling timing chain

Not run this thread into the Ground. But, I may have missed in this thread a mention of the need for a tensioner on the timing chain. Not to piss anybody off, but to explain what I know. Primarily the issue has to due to the center to center distance of the camshaft to the crankshaft centerlines. A SB Mopar's is 6.125", compared to the 5.125 of a BB Mopar. The tensioner is to control chain harmonics "slap" and to increase the life of the chain. The factory had them engineered and installed for a reason. The link below shows how big of a distance it is from other manufacture's designs.
