Hey Quenton, Have read your posts with interest. Have an 06 NE5 I have modded to your specs. Head milling, timing , porting etc. Am brewing a home built clutch system and am needing a target RPM to set my ratios with. What can I expect in top RPM in general. In the form recieved with the restrictor opened I got 38-42mph on the stock speedo(depending on planet alignment). Need to know the suspected top RPM of the modded engine to select pulley size. Thanks!
