There is a potential problem with using the tensioner on anything other than a magnum series engine. I just built a stroker 410 (73 360 LA, 040 over) and installed a Hughes Pro Gear double roller chain. After carefully degreeing the cam, I installed the tensioner (purchased from Hughes as I did with all my other engine parts). Then, when installing the OIL SLINGER, I noticed the outside diameter of it was hitting the lower corner edge of the slinger... the slinger was not square.. it was at a slight angle because of this interference. So, carefully, I masked and shielded the timing chain setup... and using a Dremel grinder, I removed a small area of that lower tensioner. Now, the slinger clears it, seats squarely... and should be OK.

I questioned Hughes (Rich?, tech line).. and he said the tensioner was never OE intended for anything other than the Magnum series engines (as well as saying they/Hughes never heard of this interference issue.)

After reading more about the potential wear issues of the material, I'm a bit concerned and hope that won't happen to me... time will tell.

PS: I sent a memo to the MOPAR Connection magazine editor about this... but he never replied in any way.
