First thing, break in the cam
First time you crank it up you need to break in the cam ASAP. If your valves are set reasonably close then it should be not problem. Run the engine over 2000 RPMs for 20-30 minutes, then the cam is broken in. Next thing I did (this is on big or small block Chevy but should apply) is double check the valve lash with things hot. Next, I changed the oil and fileter to get any crap out of the system, break in lube, metal from breaking in rings/cam, etc. Then drive it like you wanna drive it UNLESS one of your new components has some other recommended break in. In the case of my Corvette the CenterForce clutch required a 500 mile break in, so no burnouts for 500 miles.

To clarify one more thing...you can wait to start the engine or you can start it right away. If you told the engine builder it was going to be awhile hopefully he used plenty of break in lube to keep everything well coated for the wait.

First startup?
FIRST!! The engine HAS to be primed thru the oil pump!!! DO NOT start the engine until this has been done. Do not delay starting after the priming has been done.
The use of "sticky" lubes to assemble an engine is OK, but the internal passages have zero lube in them, and at startup, the oil will be delayed in getting to critical points such as the cam, until the passages have been filled.
As for "leaning on the motor", we run all our engines in on the dyno for 30 minutes,[zero to 10% load], check for problems, [and this includes cutting the filter open], once that is done and all is well, we make some low power pulls, then" let it all hang out"!
Once that's done, we drain the oil, cut the filter, and verify the engine is ready to install.

I did the complete rebuild myself.........start to finish (minus machining). I primed it properly, broke the cam in for 30 minutes and took it out for a mild run. I've been seeing only about 3 lbs. boost for the last 2 days........then I pumped it up to 7 lbs. today a couple of times. It seems much stronger at 7 lbs. than it was before re-build at 15 lbs........cool. I just hope it lasts......... When is this thing truely broken in so I can really crank it up???
