Those late model Magnum timing chain tensioners......

I think they are a waste and just something to break-wear out. Buy a $130 chain and gear set and forget the tensioner. I don' want anything rubbing against the chain. Factory came out with them for 100,000 mile smog standards and besides those engines don't scream on the freeways.

The 340's never came with them and no pro racers back then used them either--and still don't, so what does that tell you ?
