hi mate, most of whats written above is correct but all i will also say is that when on initial start up dont let it idle, keep engine speed at about 2000rpm to 2500rpm to keep the oil pressure up and also reduces stress on the camshaft faces. this is critical when running in new camshafts.

change oil and filter after 500 miles. and as for running in oil dont use the cheapest oil you can get, why use shit oil when its first miles are its most critical to bedding in properly and lasting.

do the first 50 miles or 2 hours running time to bed in the cams e.t.c. a crankshaft doenst need bedding in as they are machined surfaces that run within an oil film anyway, the crank never actually makes contact with the engine bearings.

i would give the pistons and rings about 200 miles before using revs over 4500rpm.

the other thing i would seriously think about is to get the car setup ASAP because incorrect fuelling/ignition timing can cause lots of problems from detonation, to bore washing e.t.c.
