Did you change the crank pulley using the Nove crank pulley . I seemed to notice even thouge the crank pulley on my 6 cly two fifty has has double groves already , it's not as wide as the power streeing crank pulley . The p/s crank pulley I got for my 6 banger is a grove then like a half inch space then a grove , the original non p/s crank pulley on my 6 has grove grove . I've yet to change over to p/s and not really sure why the differents in the pulleys but , that may be the off set you need . My parts are at work and I still need to learn how to post pic , I thuogh I had the measurment here at home but can't find them , wife clean out the junk draw . I could have the measurment Teusday afternoon as long as my tierd self remembers . Good luck and take care Nick
