An the rest is on the country roads taking it up to 50mph for short periods of time.Is this the right way to break it in.
Thanks for any feed back

Don't know how many folks actually followed that advice though | | | | | Joined: Apr 2005 Posts: 28 Junior Member | | Junior Member Joined: Apr 2005 Posts: 28 | hopefully you've already changed the oil once | | | | | Joined: Mar 2005 Posts: 75 Member | | Member Joined: Mar 2005 Posts: 75 | This is how I break my motors in that I have build, three six, four v8's chevy of corse. after getting every thing set and the cam broke in, 2000 rpm for 20 min. I run it as hard as I can like the way that I will drive it later. if its going to break it will do so then. with the six's I go do hard burn out's 5 to 15 min. each with old tires to run the rpm up high. the six that is in my truck now is 19 years old. after the rebuild. know a lot of people that Baby the motors for the first 500 miles and the first time the stood on it it broke something. with all of the engines that I have built none have give me any problems.
