It's non-trivial. Which is why I figured I could balance a little
of it with the removal of the fan. It's actually driven off the
water pump, but it's a load on the engine in general.

Unfortunately, it's a long block from another party and I wasn't
planning on tearing it down before installation. At least not if I want
to install it this year.

True. Maybe I'll just bite the bullet and call BFE...
