Breaking in a new built engine
I've just gathered the parts to build over my engine (crank, pistons rods, bearing, etc) but before i get started, What would you just suggest for breaking it in? I read everything from let it idle for 30 mins and just change the oil to run it in -ve boost for the first 1000 miles. What Oil would be recommend for the break-in periods?

I'm a firm believer in hard break ins. Don't use synthetic for your first couple of oil changes. Prime the engine really good before the first startup. Once it's running, let it idle until it's completely warmed up, take it for a light drive. Then change the oil and drive it like you stole it for about 20 miles. Change the oil one last time and do a compression check. If all is good then have fun.

I think it's more of a why waste the money on synthetic when your gonna dump so frequently at the early break in stages. Can't see any other reason really
This is what I meant by my first post soooooo much conflicting/I heard from XXX info. That what really the end all be all is to consult your builder and follow their recommendations

ahhhhh. the conflicts!
I guess i will try the "safe" route.
30 min idle break in with RP break in oil.
1000km with RP break in oil.
Amsoil engine flush and then amsoil 10w40 high zinc.
Would have liked to know the proper/best results approach though.
