Hi Ken,
Thanks for the very quick reply.
You are right... but I'd better have a dozen of coherent and identical US
second advises than just trusting a reputable European engine builder who
has built 25 Cleveland in his 40 years carreer. That's what a US builder
does in one year or so... . I have experienced several disappointments in
building even street engines in the EU, that I had all my race
engines satisfactorily built in the US, even if, sometimes, there are some
troubles. Life is like that. Nobody said building engines and putting them
in a race car ( even a Pantera ) are an exact science... Especially when it
comes to about 100 HP per liter with a normally aspirated engine whose
conception dates back from the 60's. Look at Formula One or World Endurance
Championship ( WEC ) today, There, we are talking about the best engineers
worldwide , and practically a no limit budget . There is a persistant
rumour saying that Mercedes Benz left a one billion euros cheque on the
table for its F1 hybrid engine.
Asking "obvious" questions to the Forum has always been THE solution for me
when I was " desperate" : fast, experienced , detailed, accurate AND
friendly ! I cannot thank my Forum friends enough ! The Forum saved " my
life " overnight for Le Mans Classic 2008 with Candy, I will never forget
that .

Hi Pat,
If it's internally balanced, I think it should be a neutral balance
(not the 20 oz balance)A flywheel.A A Cleveland and Windsor should be
the same, but with a ZF, you need a 164 tooth flywheel.A A lot of
flywheels have removable weights, so you just take off whatever weight
is on it.A If you want it really good, have the flywheel and pressure
plate balanced together toA zero.
If the engine builder there does not already know this, he probably is
not the right builder for your engine.

A I have closed my relationship with my "fancy and moody " US engine
A builder . Those who know him had warned me about him a long time ago
A and I must now admit that they were partially right ... After the
good
A part, I now take the worse part, and the "fancy" bill, of course
:>((
A This " gentleman" sent me back my unfinished race engine at my
request.
A It A "only " needs flywheel, dry sump system and clutch.
A Here is what he writes to me : "As far as balancing the motor, it is
an
A internally balanced motor.AA If you have further questions
regarding
A how to set up this motor or finish, please refer to the mechanics
your
A are using locally as I have stated previously, our professional
A relationship is over."
A US engine builders are so used in building Ford V8 engines that I
A always had my race engines built in the US vs.EU, despite what I was
A advised over here. I shall have this engine finished over here, but
A would like to be sure of what a local ( competent ) builder will
tell
A me to finish this (expensive) engine will be the right solution.
What
A do I need in terms of flywheel? It is a Windsor based engine, NOT a
A Cleveland ( see pics ) . When I bought it ( broken ) three years
ago,
A it was supposedly delivering 640 HP.... But it has now been fully
A redone, while keeping the " good" pieces
A Many thanks for your advises.
