I think your gonna need to use Ford Racings pn# M-6500-S58. These lifters have a "tie bar" that you will most likely wind up using rather than the "spider" from the 91 motor. The spider mounts to two or three bosses in the lifter valley, but I'm thinking your 289 won't have these bosses.

You will need to use a roller camshaft. Personally I'd consider using the 91's camshaft. If I remember right gross lift is around .440" and duration is around 210° on each lobe. You'll probably have to get cut to fit push rods.

Let us know how and where this goes!
