I got a 347 stroker in the process of being built. I'll be following this link for break-in
http://www.mototuneusa.com/break_in_secrets.htm and also following what the guys on hardcore5.0 say: Get it warmed up and take it to an open road and take it up to around 4000, 5000, 6000 a few times under a low/medium load and let it coast down in gear. Do this a few times varying the load, rpm and speed then come home and change the oil and filter. Then from then on I would think just drive it as you normally would but i'd also vary the rpm and speed and I wouldn't be afraid to abuse it to. What you don't want to do it get it running and drive it like an old person for "1000 miles". Thats incorrect.
Congrats Allen. Big accomplishment, its amazing what we can do if we put our head into it. Did you build the shortblock or did the machine shop build it and you put the h/c/i on?
Yea,
I've heard two different schools of thought on this subject matter, and was curious as to which one to go by. I mean, I want the ideal break-in procedure. On one hand, when someone buys a new car, there is nothing mentioned about an extended break in procedure(1000-1500miles), right? But on the other hand, many people have done it that way for years, and have had no problems with it. Will driving the car the way grn92lx has in his post hurt the engine at all? thanks for the help guys,
Lenny
