Pre oiling after sitting for several years

I am going to pick up my LS1 this weekend. It will be several weeks before I fire it, but this has been in the back of my mind for a while. I have done lots of google university, but I wanted your opinions.

The motor has sat unfired for 4+ years. My plan is simply to pull the valve covers, wet the rockers, crank it for 3x10 secs with the coils/fuel pump fuse pulled to spin the motor up, and light her up. I realize that this isnt the BEST way, but is this a reasonable solution? The goal of this swap is to build an affordable DD with good mileage, not a purpose built track motor... So, I am less freaked out about such things than I was with my BBC.

Will I need to keep my rad cap off to bleed the air out or will the steam port make this unnecessary?

The motor is a stock LS1 out of an 02' F-body with 60k miles (according to the PO, unverified of course).

Re: Pre oiling after sitting for several years

That's what I did and it worked out. I kept turning until it registered pressure on the guage. My 5.3 sat for 5 years in the garage. There is a special pre oiling tool for LS engines but it's a little expensive. I had to run with the cap off at first, got a ton of air out. Even with the cap on it still felt like forever before the tstat got hot enough to open.

Re: Pre oiling after sitting for several years

The best way to fill the engine with anti-freeze to prevent an air block is to fill the engine/radiator through the top radiator hose into the engine. Once the radiator fills to the open top hose return, put the hose on and finish filling in the radiator.
