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

My Harley uses a nylon chain tensioner, replacement cycle is 25-30000 miles. Too many twin cam engines have had failures with tensioners.

I don’t run them on my small block LA or big block RB motors. I really don’t think they hurt or help, but my opinion is why put another wear component inside the motor that could possibly fail.

If one was really concerned with absolute timing accuracy, get a gear drive..
