318 timing mark

What the guys said: both are internally balanced so the 273 dampener is fine & will have the TDC slit on the pass side at TDC. the 273 T cover will have the marks on the pass side to match that. the iron pump will put the hose on the dr side which will match your dr rad nipple. All good! just mix and match pulleys/spacers to get the belts lined up & proper fan to rad clearance (different between schroud and no schroud apps)
