[DeTomaso] Damper

[Doug Braun]

Not to worry, here are the specs on the Pioneer 872027 damper:

Dia: 6.2"
Imbalance: 28.2 in-oz (stock Ford spec)
SFI 18.1 approved
Material: 1045 steel
Damper type: bonded elastomer
Bolt pattern: 351C 4-bolt
Weight: 11 lbs (so it has enough mass to properly damp the 351C crank.  Our
esteemed Jack DeRyke has mentioned in the past that some 351C dampers may be
too light for the task)

        In case no one else mentioned it, to use the original pulleys, it
should be a 4 bolt damper.  A lot (or most?) of the SBF/SVO performance
dampers are 3 bolt.

          Dan,

              The Pioneer 872027 may be equivalent to the Powerbond
PB1082-SS, and if so
          here's the Pioneer version for well under $200.  This is the one I
bought.
          If Mikey bought the Powerbond version, maybe he and I should swap
pics of
          our dampers to see if they're identical.

          > Anyone knows where to find a hm damper for the 351C?

          I assume you're looking for a standard elastomer type damper and
not
          a viscous or Lanchester type damper.  I'm not a fan of
Professional
          Products, Pro Form, TCI, Fluidampr or Engine Works harmonic
dampers.
          The good ones are FRPP, Powerbond, Innovators West, Romac and BHJ.
          ATI is good too but expensive.  Powerbond is an Aussie company and
last
          I checked is making the Pioneer SFI-spec balancers.  For a 351C,
the
          FRPP damper is p/n M-6316-C351.  I recently sent Mike Drew to Alex
          Denysenko at Money Maker Racing for his balancer.  Alex's email is
          monymkrssla at aol.com.  He sells at least the Powerbond and FRPP
parts.
          I think Mike said his was around $250 and I know Alex ships
overseas
          (tell him I sent you).  FWIW, I've got a Powerbond SFI balancer on
the
          dyno engine, an FRPP on another and Romac on a third 351C.
