Dude, I need closure.
This thread is fuckin' scary, as I could see myself going down the rabbit hole just as you have done. One thing leads to ten others.
Did you ever go back on Marc Pringles or whatsever his name was, the ebay douche who sold you a boat anchor?
Is there any reason in your mind to not get the bulkhead galvanized? It is out, you will never have the easy opportunity again.
You are going to all this time and expense, hope you checked specs on oil pump. You have easy 3K into this motor from what I can guess, hate to see it grenade.
Are you going to talk about the injector pump at all?
VVT - are you uprating the IC?
