When to switch to synthetic oil ??

I just finished up my built 5.0 fox motor. It's my daily driver and I expect to do some track passes every now and then . It has about 400 miles at the moment. I already used break in oil for the the first 50 then put in some castrol 10w-40. I would like to run a full synthetic oil at some point but don't know when is best to start using it?

My initial break in oil procedure is this (and this is just ME but its worked well):

-Cheap autozone dino oil for the first starts, tune and 100 miles
-Change out with a good conventional till 1000 miles
-At 1,000 miles change over to whatever oil the engine will get for the rest of its life.

I generally use Mobil 1 on a "built" motor because it is really good and still cheap at $27 per 5 quart jug at Wal Mart. Failing that Wal Mart's Super Tech is a very good alternative and about $9 cheaper per 5 quart at $18 and Motorcraft Syn Blend is very good too at the same price as the Super Tech. Always use a WIX filter (NAPA Gold) while avoiding the Fram orange death cans.

Yeah, the frams are the worst you can use. Clogg up sooo easily and deteriorat inside the filter. Actually had a car that had a a fresh oil change and lost oil pressure, took the whole pan off to put a oil pump in just to find out the filter fell apart inside and the honey comb chunk got stuck in the end.

So far Scotty is on point.
