balancer questions

do the ati balancers need the spacer like the i/w balancers ? i am trying pick out a balancer for a 557. from what i have read ati, ford racing, and i/w are all good products. i noticed ati had a few different balancers. some were little over 6" o.d. and some little over 7" o.d. so what is the benefit of one over the other ? also noticed they had 3 bolt holes for the pulley.  dont most ford pulleys have 4 bolts. or was that a generic picture.

I believe the three bolt pattern will use big Chevy pulleys and it will still use the spacer.

The I.W. unit for the std long snout are 4 bolt.....the ones for the shorter Boss style snout are 3 bolt chevy patterns.

Is your crank stock long snout or short? Belt drive or chain?

timing chain and it's a probe rotating assembly (crank is built by scat i believe) so I think it's long but not sure. Haven't got it out of the box yet.

So the spacer is used with all of the balancers ? What is the reason for 6" and 7" diameter balancer ?  Bigger balancer absorb more ?

Mine is a 7" ATI

Pump and accessory clearance, crank triggers, an option for options....

Those I/W's sure are pretty

Do all of the balancers take a after market timing pointer ? Or can a factory pointer be used ?

The I.W. short snout dampers do not use a spacer...the only one that I'm aware of that does not .

Are all the neutral balance spacers the same other than material there made from ?

With the IW long snout can you use the factory spacer or does it have to be shortened?

very similar.

Yes. And don't fear the aluminum.... searched high and low to get a "iron" spacer. Aint worth the headache.
