No, I wish I had those type skills. I can't get the tig welding down. I do custom exhaust, the guy that built it worked for me at the time...he has his own shop now.
And I'm retired...only do it when I want to..can't seem to stop.

What dry sump are you planning on going with? I wasn't aware a dry sump pump could pull vacuum on the crankcase and pump oil? If an oil pump is sucking crankcase gasses then it won't be pumping oil. Or are you planning on running a vacuum pump in addition to a dry sump?

Todd, With a dry sump, you usually have 2-3 stages of pump sucking oil out of the pan and pumping it back to the tank and 1 stage pumping oil to the bearings. Since the 2-3 stages are more then are needed, they suck a lot of air since they are gear pumps. When you seal up a motor really good with no PCV, then it creates vac inside the motor as if you had a vac pump on it. All our NASCAR motors were this way.

Also, I saw a couple motors that were built by kenny Dutweiller at his shop that were running a dry sump system and I told him of my plan to run a belt driven vacuum pump off the motor and he kinda re-organized my thinking on how to properly get the vacuum I needed for a street driven car in a better way. Basically one system alone can't get the necessary vacuum but a combination of a few or tweaking a Dry-sump system will work. Also I have a few turbo/engine building books laying around that talk about it in more detail. Trick is to find a system or small combination of a system that will be reliable on the street.
Oh, and don't think that the ZR1 pulls that much vacuum on their pump though, in stock configurations they are doing much less than what can be done with them.

Psssssshhhhhhh, who needs freeze plugs and head gaskets anyways! I'm gonna do like Porsche Racing and weld my heads on.

Updates are...
I just got back from a 5 month stint overseas so I haven't been able to do anything on the truck since early May.
However, truck is on jackstands and completely torn apart. Engine's been at JFRacing engines since early summer and I should hopefully have it back in my possession in a week or so after being rebuilt, specs on the motor will follow once I get it back.
Starting this weekend I will start work on the truck again, I am pulling the whole fuel system and starting from scratch, after which I will be cleaning and re-assembling this truck from top to bottom.
I just bought a new DD so finishing this truck as fast as possible is not necessary anymore. I hope to have it up and running by Christmas, I still have lots of research and purchasing to do.
