Breakin for warmed over engine?

HI,
Did a very quick down and dirty warmover for my 350 sbc. It was in great running shape when I pulled it from the donor truck. Took off the intake, heads, all accessories (water pump, fuel pump, etc), and oil pan. Replaced the oil pump, water pump, alt, fuel pump with new stuff, cleaned the heads and intake up and painted them, and put it back together. Like I said, quick down and dirty due to money, for now. Question is, break in. Since cam and pistons and mostly all the internals were not touched, do I need to do a full break in proceedure? Or a modified watered down version? What would you guys reccomend? You never steered my wrong yet, thanks!
Zak

No need for a full break in procedure. IMHO
The main thing i would do from what you said you have done to it,
i would at least re-prime the engine and make sure everything is oiling good before start up since you did replace the oil-pump. Everything else should be fine.IMHO-JMO

kinda what i figured. What about break in additive, is it a waste for my situation? I have a nice oiler, used a old distributer, ripped it down and ground off the bottom gear. Hooks up to a drill, works beautiful, so repriming is no problem. Thanks!

I really wouldn't worry about putting any break in additive in it myself the engine is already broke in . JMO

Breaking in an engine mean you are mainly seating the rings to the bores, and if you have a NEW flat tappet cam, seating the lifters to the cam, that's about it , but since you didn't mess with any of that their is no need.

Yes I did. I did research this project a lot before taking it on. I took 300 pictures of dissasembling the engine, and individually ziplock bagged each piece or groups of bolts and labeled it. It may be overkill, but I wanted my first rebuild to go smooth. So far, it is working out really well.

There's no such thing as overkill when you're re-using the orig. cam/lifters. It's like ...measure twice and cut once. You did the right thing.
