I thought about that myself. As a matter of fact cloyes makes a stock replacement V6 tensioner for not too much coin, about $30, and mopar performance used to offer theirs for a V8 app in their catalog. I think the problem is that the nylon tensioner shoe is not wide enough if using a beefier and wide double roller chain to allow it to ride against the full width of the chain. I believe it was designed for use with stock type single roller chain sets. Now if building a mild small block with a stock single roller chain the tensioner could be valuable since those develop chain stretch and slop pretty early.
