Timing Chain Tensioner 318/360

The owner of Milodon pointed out to me that the Mopar small block motors have one of the longest cam to crank centerlines of all V-8's! The longer that distance, the more chance of stretch. Mopar small blocks are notorious for loose chains.

One reason I heard for the factory tensioner was to reduce timing chain noise that custormers complained about.

I installed a real nice Rollmaster timing set on my new motor. It felt real tight. Then we degreed the cam. THEN we added the tensioner and degreed the cam again... ONE degree difference with the tensioner!

One degree might not sound like much, but that was a brand new high quality chain.
