390 pulley's

[wolfpupsdad]

 after alil research work i'm working againist a dead brain and CRS. not to confuss the fact that it's been years sence i've played with ford FE motors.
  heres my dilemma. i need a set of dual groove pulleys for both the water pump and crank. NOW if memory serves me right, if the crank damper hub has three bolts holding the pulley on , its a 67 or later motor, as long as the damper hasn't been changed. and any pulley set up with three bolt will interchange? is this thinking correct or em i off base?

wolfpupsdad,
    I've got a 390 in my fairlane. The only kind of pulleys I've seen have three bolts. Make sure you get the smallest water pump pulley you can find. I think I ended up with a 6 inch pump pulley. Makes a big difference while idling. It only has to have one groove if you aren't going to run air conditioning.
    I've interchanged 360 and 390 crank and pump pulleys without having any problems.
