I Agree with Craig. There would be so little change in the valve events ( when they open and close). The chance of burning valves is to high for me to gamble on this one. Look at the differances between stock US and Euro cams. Big differance, not a huge power gain though. A couple of thousand's will only move the valve timing about 1 to 2 degrees. |

I set mine to the high side 15-16 thou. My concern was burning a valve if too tight. I don't think you're going to see any difference in power between 14 and 16 thou. anyway.... |

Another 328 service related question: my owner's manual (1987 328 GTS) provides valve lash settings of intake: 0.008-0.010 in. ; exhaust: 0.014-0.016 in. The service manual lists metric lash adjustments: intake: 0.20-0.25 mm; exhaust: 0.30-0.35 mm. The metric to English conversion indicates that the intake clearance ranges are nearly equivalent. However, the metric specification for exhaust valve clearances converts to approximately 0.012-0.014 in., tighter than the clearances given in English in the owner's manual. If I set the exhaust tighter, I will effectively increase (only slightly) the valve duration. What valve clearances do these motors like? Thanks in advance. |
