Well after a long 11 hour day of fun at work, I went looking for my other balancer off the 403 to replace old denty. Found it, blasted off the Duplicolor with aluminum oxide and painted with a couple of coats of VHT Black Metallic Engine Enamel. I also removed 20 pounds in the form of the removal of the POS R4 with a delete pulley.
Dude please don't use that balancer...if it is not a replacement it's at least 42 years old...you have to much invested to use a used part like that. Both my Olds builders refused to use an old balancer on my engines...JMO

I will discuss this with Mark. This one is in good shape.

Decided to glue on this gasket to the reverse rotation Flowkooler water pump. Since this gasket does not exist outside of buying this pump, gluing to the pump is much more ideal than the cover. Of course, I used the best RTV on the market.

Talked to machine shop today, the crank is ground! It is .030"/.030", they need rings and rod bearings to internally balance. I told them to get me rod bearings to speed it up, nope. They called direct to manufacturer's, Clevite, Federal Mogul and King, no one had any in stock. Sent Mark a message with the rest of the parts needed, hopefully they are available.

They should be able to estimate the weights to get it balanced. A couple grams either way isn’t going to hurt it.

Something to think about... I'm no expert but I'm thinking that nobody has the .030 / ,030 bearings in stock is because it is not ideal. I think we can all agree that .030 is pushing it. The potential problem is that some mfgs use the same size outer shell, and then use thicker ( softer ) bearing material, while others use a thicker outer shell, and and thinner bearing material. If I were you, I would call Clevite, and King myself and talk this over, before making a decision. Maybe 64nailhead has some insight. I'm curious what Mark has to say.

I agree with this.

Remember this is a 330 crankshaft, so it is way stronger than the lightweight POS crank this block came with but is heavier. There is actually .040" bearings available for the SBO from King. I will ask Mark this question.
