Question: What is the Best timing chain setup LA or Magnum

tensioner v. no tensioner will be a war still being fought long after you, i, and these cars are gone and continue to wage until the heat death of the universe.

top quality true double roller no matter which shoe you put on which foot, though.

preferably something that has keys for adjustment.

summitt billet true roller, edelbrock, melling 40202, cloyes billet true roller, roll master, PRW billet. there's a wide swath budget wise and advance/retard adjustment as well as availability.

i have a feeling that the trick flow and summit billet are the same piece. edelbrock doesn't make their chain, but whoever it comes from it's a nice piece. stay away from the lower tier cloyes and anything that says "link belt". i wouldn't roll dice on anything comp makes, especially when there's another option that's proven is only 10 bux more.

i got jammed up on a job-- straight up beer budget rattle bomb rebuild-- and wound up having to go with the dayco KTC1448. there's no provision for adjustment, but it's a true double roller and i thought that the fit and finish was fine VFM wise.
