So Chance,
...did you drill your own countersunk holes in the Fidanza flywheel for
these shouldered bolts?

  These are the shouldered bolts that I used with my Fidanza Aluminum
Flywheel and they worked great.

  However, I cant comment on the flywheel because my motor has only run on
my test stand:(  and currently resides there while I work on the car body.

    I bought a Fidanza flywheel and found it disappointing in the fact that
the
    correct bolts for the Ford pressure plate couldn't be used. The stock
    flywheel has a countersunk area at the top of each threaded hole. This
    allows you to use the factory FORD type bolts with a short shoulder
under
    the head. That shoulder registers snug with the holes in the pp cover.
The
    Fidanza flywheel I got didn't have the countersunk area and the
alternatives
    are not great. You can use an non-shouldered CHEVY type bolt which
leaves a
    bunch of sloppy clearance and only the threaded portion of the bolts in
the
    pp holes because there is no shoulder. Or, you can countersink the holes
    yourself, but in the aluminum Fidanza flywheel that will leave a
    questionable depth of thread due to the lack of thickness where Fidanza
    drills the holes. Others have said the CHEVY style bolts will work, but
I
    think it's very poor engineering to retain a pressure plate from
rotating
    back and forth on the flywheel that way. Centerforce flywheels have the
    proper FORD style countersunk holes. I haven't had one, but I think the
    other makes like Hays and Schaefer have the correct pp holes in their
Ford
    flywheels too. You get what you pay for.

    Others may feel differently, but I wasn't happy with the Fidanza.

    Hello all. I am having a new engine built by Russ Fulp Racing in SoCal,
and
    was wondering if anyone has used a Fidanza flywheel in their Pantera? I
had
    a Fidanza flywheel in a Mustang previously, and was pleased with the
quality
    of their product.

    I need to buy very soon, so please share your experiences to aid in my
    lightweight, flywheel purchase.

    Thank you!
