I am going to fire up my rebuilt 5.0 this weekend, what is the recommended procedure for breaking in a new engine?

what kind of oil is in the motor? when you first start it up do not let it idle you will foul pulgs. also what did the directions say for break in on your rings?

break it in like a new car 500 -600 mile pampered then change oil then you should be good to go

i agree you have to take it easy for at least 500 miles

Actually im going through the same thing now and i plan on taking a trip from LA to San Francisco and back. Thats about 650-700 miles from where i am. Find a nice route and take a little trip with her to break her in.

Thanks for all your input! I was given this link to a good break-in procedure, this is what I'll go by.

i thought it had to be stop and go driving not just a long road trip

As long as the rpm is varied a lot during a trip, the rings should seal up good. Do not use cruise control or stay at one engine speed for very long.
