Well, it's finally back in the shop. We are installing the pullies and a custom cam first, then it will get moved over to the other side of the shop to get the fuel system designed. I will get more pics as it goes on.
This pulley configuration will achieve maximum efficiency blower speed at 6500 rpms.

Yes, that is a catch can, and yes we were draining it. I check it once every month or 2, generally 1-2 ounces of oil. Yes, I think it is a good investment.
