[DeTomaso] Pantera water pump pulley?

[doug351c]

Mike,

Here's what I found in my garage.

70 Mach1 351C4V
  water pump pulley = 6" dia x 3"Long overall
  crank pulley = 6" dia

73 Pantera 351C4V
  water pump pulley = 5.5"dia x 2.25"Long overall
  crank pulley = (can't find it right now but I bet it's 5.5" dia)

I'm betting that the Pantera pulleys are special and should be treated as
such.  The smaller diameters help to keep it all within the confines of the
bulkhead cover.  The only reason to use something else would be Jack
DeRyke's primary reason.  At 2.85# my pantera's water pump pulley is HEAVY
!!!  And so is the crank pulley.  From what I remember of the Mach1 pulley
when I last had it in my hands, even though it's larger, it's lighter.  With
these pulleys being rotational weight, it's even more important to lighten
them.  The engine will rev faster.

Hi guys,

I recall that the Pantera crank pulley is unique to the Pantera (two
sheave, four bolt, of a certain diameter), true?

What about the water pump pulley?   I recently had a pair of Ford 351C
water pump pulleys fall into my hands--one from a Pantera.   Their offsets
are
very different from one another.   Is the deeper offset Pantera pulley
unique
to the Pantera, or is it fairly common?

I ask because if it was special, I would take the time to sandblast and
paint it and offer it up on E-bay as a Pantera part.   But if it's just a
generic Ford thing used on zillions of cars, then it might not be special
enough
to warrant my attention.

Looking forward to your thoughts...

Mike
