Timing chain recommendation

Damn I hope not. Lol your probably right tho. Everything else "budget" I have bought has turned to **** so that won't be any different. Haha
IF you get at all Concerned, look around for a 'Rolon' Manufacture Chain: True Roller & only 3% less stretch & stress test back to back to Iwis & far cheaper - JP use the Rolons Std, you Want: DR (double Row) then the number of links as the Suffix (SR if your Enginetechs gears are single row)
Seeing there's so many X-spurts.

Short of Changing the Cam, Slip in a 2-4° Mr Gasket offset Crank-key in the advanced position on fitting the Crank gear (& new seal in front cover) help wake up that 318.
Goodluck. T
PS just noticed you bought the D/row Engtech set probably be an Asian Chain (.. Look on the side of a link: Taiwanese, they're ok) But I wouldn't worry, unless overly sloppy & that takes experienced hand, but Follow above IF you want some extra insurance: any nos chain with " USA Made" on link or Rolon & rest assured.
