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
