With what engine and what chain set? I have hears tensioners and double rollers don't play nicely together.
Was looking to use the Edelbrock true roller 7803 timing gear set on my Magnum 360 but I read in the description on the JEGS website that it is not to be used with hydraulic lifters. No mention on Summit or Edelbrock sites so I called Edelbrock Tech support and they said it will NOT work on Magnum due to clearance issues with the upper sprocket. They recommended a Cloyes unit. Now if someone wants to dispute this with real world results I would still like to use the Edelbrock set.
