About to assemble my forged 347, what's the break-in procedure?

Non-synthetic oil?
RPMs below a certain level?
Vary rpms?
Boost below a certain level?
How many miles for break-in?
When to change oil?

 

All of the above. Change oil at 500 miles. Break in time depends largely on the type of rings you used and the RMS of the cylinder crosshatch.

 

Thank you.

 

I agree with what 30thWs6 said.

 

um, leave the boost out of the equasion until the rings seat in. you'll have a tough time with making a good seal otherwise. should only take about 2-3 weeks of normal driving. and after the oil change, (back w/ non-synthetic the first change, synthetic when your 125% sure the rings seated.) put the bost to it and start flyin
