Bob,
Thanks for the reply. I am installing the Fidanza flywheel. Got the
collar type washers, but have decided not to use them [ordered wrong
size anyway]. The ARP bolts have a sufficient unthreaded under head
length to make a very secure fit in the flywheel. I think I might do
more harm than good having to enlarge the flywheel bolt holes enough to
hold the washers in place.
Just my plan and two cents worth. I know you mentioned there was a fit
problem with the Fidanza you got. They must have fixed it. I heat mine
up to 250 degrees in the oven [so it will expand and fit over the end of
the crank boss], install it, and the bolts line up perfectly. Got it
all torqued down, then realized I had forgotten the pilot shaft busing
for the snout of the tranny. Of course, it grew legs so I have had to
order a new one from Herman as it is for the Toyota tranny conversion.
Waiting for the new front axles for my new Southwick hubs before I
reassemble the engine, as I do not like the cam to sit in an unstarted
engine for too long, and the wife would go nuts if I started it and ran
it at 2000 for twenty minutes in its current location -- the garage
aimed at the furnace intake.

I don't know if this is an ARP number or not, but www.aptfast.com lists
the PN for TR6 flywheel bolts as: FBT716-4 (4 is the number you need).
Note too that this bolt _requires_ a special washer. Call APT for the
numbers. I would guess that 716 is shorthand for 7/16 which is the
diameter of the bolts... so maybe this is not an ARP part number. I do
recall that the ARP catalog actually lists TR6 and GT6 applications,
although _BE CAREFUL_ with what you order because some of the
recommended numbers are more for race motors than street motors. For
example, the head bolts that they list are only for heads that heve been
milled quite significantly.
As for the flywheel bolts, these parts are CHEAP. It's like $14 for the
bolts, maybe $20 with the washers and shipping and everything.
Note, however, that the bolt listed has a very short grip area. If you
use an aluminium flywheel, you may want to use part # ARP-230-7303 You
need 2 (3 bolts to a pack ) which has a threaded area that is a bit
longer.
You can buy ARP from Jeg's and Summit Racing.
The quality of the ARP parts that I've used can not be understated.
While I do check these parts before installing them, I have yet to have
to "dress" them before installing. The same can _not_ be said for a lot
of the parts that we see nowadays. I'll post another message on that
topic in the near future.
:-)
