Here's the thing, it's a REW Block. It was balanced, there are holes on the rear counter weight and the front hub. I imagine this is how they balanced it.

Anyhow, I wanted to use my dual main pulley. But, that replaces the hub.

Will that throw off my balance?

Here are pictures for reference.

Its just like putting a flywheel on your CW. Nothing is going to change...

 

hey is that a 1/2 IPS or NPT fitting you have for the oil line. In other words is that the same a gas stove flex hose adapter?

 

Where'd you get that water pump?

 

I just wanted to make sure everything will stay in balance.

Do you know if that front hub is balanced from the factory like that (All the holes)?
