But ................ 120" has a 4.25" bore and 4.25" stroke
.......................131" has a 4.25" bore and 4.625" stroke
Pull the timeing plug off and turn it over till you find some numbers on the flywheels ............... if you find them google the numbers and try and see what stroke you have! ................ seems I remember the middle part of the wheels with say 120 ............ 131 cast into them but I maybe wrong on that!????
