mattscort Posted August 21, 2010 Share Posted August 21, 2010 Any one know standard valve sizes for 1600 Xflow (valve face diameter and length)? Google has failed me and my manual is missing a few pages. Quote Link to comment Share on other sites More sharing options...

RUNAMUCK Posted August 23, 2010 Share Posted August 23, 2010 Hijack, but what are the differences between the 693M and the 711M? I've heard that the larger sized valves can be used as an upgrade for datsun A series. Quote Link to comment Share on other sites More sharing options...
Unclejake Posted August 23, 2010 Share Posted August 23, 2010 ^ The numbers you quoted are block designations aren't they? These motors are a bit old fashioned but the valves are in the head Quote Link to comment Share on other sites More sharing options...
