Default Cam swap, first start up procedure

I'm doing a CC503 cam swap and installing a Yank SS3600.

I'm also doing oil pan gasket, rear main seal, head gaskets, and just about every other gasket/seal on the engine while I've got the engine out of the car to put the stall converter in.

My Question(s) is:

1. Since I have this engine stripped down to a shortblock, is there any kind of oil system primeing I have to do? I know when you build an engine you have to prime the pump and such, but I'm assuming I dont have to because I never took the pump off the engine. I just wanted to check with someone else to make sure I wasn't crazy. Do I need to prime anything? (other than letting the new LS7 lifters soak offcoarse)

2. I've done enough research to find out that hydraulic roller cams dont have a break in period, so I just need to change the oil after 100 miles or so to degunk things. But, do I need to run a certain type of oil to start out with? (reg or synthetic?) I run Mobile 1 full synthetic normally.

Thanks for reading
Ben

1) no

Not that I am doubting gregrob^, but does anybody else have an opinion or maybe agree with the above theory? Simply for reassurance purposes...


Thanks

I agree, run whatever you're gonna run and change it after 50 or so miles.

Agreed. Also, go ahead and put some oil on the cam lobes when installing it.

Personally, I'd just use some cheap petroleum 10w-30 or Diesel 15w-40 for the first 50-100 miles and then drain and fill with the oil you plan on using. I like to think of it as a flush for any particle contamination you have gotten in your motor during the the work. I see no use in wasting expensive synthetic oil if you are basically flushing your motor.

I agree. Come to think of it I just tossed in some cheap Pennzoil dino oil I had laying around when I did my last cam swap. I usually run sythentic Amsoil but I wasn't going to drop $50 on oil to drain it out only 50 miles later.

That's what I do. I run to walmart or if checker has a super cheap deal on oil. I don't see a point in wasting 50 bucks for oil to drain it so soon as well.

That's what I did. I also poured about 3qts thru the top of the engine down the LIFTER bores and right back out the pan before starting. A little extra insurance.
