What is the price on a Moldex these days?

and that
you still have a stock crank that is by no means bullet proof.  IMHO  
spend the
extra $ and get a billet crank.  The billet crank with some Pauter  
rods make a
very durable bottom end. That is what I did 11 years ago and have not
regretted it.  My Moldex crank even survived a dropped valve, which  
destroyed
pistons and Carrillo rods.    Joe(B)

I am preparing a fresh crank ( stock ) for next season and I want to do

everything I can to bullet proof it. I will start with Magnafluxing  
it, then

shot peen, then cryo treatment, balanceB and finally nitriding.

I have had my issues with # 2 main in the past and I want to improve

( if possible ) the oil flow and or volume as best I can.

I have heard the passage in the crank can be drilled out a bit and also

heard the angle of the passage can be changed to better apply oil to

the bearing rather than scrape oil. This will also give me the  
opportunity

to try Chris's new rear main seal.

Also, has anyone tried different oil pick up configurations or  
manufacturers?

Any advice would be appreciated.

Thanks,

Jim G
