Starting rebuilt engine for the 1st time

[Onefast99gsx]

Hi guys-

I hope to start my car up for the first time later this weekend. It's a fresh rebuild. I packed the oil pump full of vaseline and of course used assembly lube on all the bearings. Other than adding oil do I need to prime the engine somehow to get oil into all the journals and head?

My engine shop said they have some sort of system where they put a quart of oil or so in this container thing and hook it up to compressed air and tap into one of the plugs on the oil filter housing and it shoots oil into the motor. Do I need to goto that extreme. Don't really want to push all the assembly lube out prematurely.

btw- I redid the timing belt tension like 6x until I found exactly where I wanted the tension. Then of course each timing you have to rotate the motor over and let sit for 15min. So I'm sure the cyls are getting dry. I didn't get the engine in last night like planned. Would it be a dumb thing to add oil as normal, then physically rotate the motor upside down or close to it for a second in the engine stand?

Thanks.
