NismoZ Posted February 14, 2007 Share Posted February 14, 2007 First off i would like to say hi and thanks for looking..Anyways I have just purchased a 72 z..I have a little question though about its engine that i dont know much about..I wanted to adjust the valves and clean the carbs if needed but i just realized its not stock..it has a N47 head with a l28 block and some stock SUs and im guessing a cam since it has a lope..what would be some good specs for valve clearance?stock settings or somthing differant?

24ounce Posted February 15, 2007 Share Posted February 15, 2007 i would clean it up and tune it up all to stock l28 specs then see what that gets you - your lope is probably from poor carb adjustment Quote Link to comment Share on other sites More sharing options...
