Ok, So I never had to brake in a fresh engine befor so... I want to know whats the proper way to do this since I hear soooo many different myths and stories... It's got me threw a loop. I just want to make sure my LT1 is getting the proper brake in to avoid any damage!

Here's one article I found http://www.howtodothings.com/automotive/how-to-break-in-a-new-engine

I also found this in another article

"High performance engines differ slightly from traditional engines and a wider range of speeds should be employed during the early stages of engine use. Consult the motorist handbook supplied with your vehicle for full information of speed recommendations.

It is also suggested that performance engines are never left to idle for any longer than a couple of minutes."

Suggestions ??? Kinda lost... Someone told me not to go over 45mph and someone else told me to go on the highway and cruise at different rpms/speeds....

Is this engine actually completely brand new, never started at all? Rebuilt? New, but has some break in time on it already?

X2. Is it a crate motor or one that's been dyno tested already?

Thanks. I suggest you give them a buzz and do exactly what they tell you to the letter. If you don't, they could deny a warranty claim later on (and have a leg to stand on).

Each Engine is pre-lubed and spin tested for proper oil pressure, oil flow, compression, and general operation before packaging.
Sounds like they have no actual run time.

I agree....contact them and see what they have to say.

I remember when i got my reman from jasper they actually told me not to keep it at a steady MPH.

but more importantly then listening to everything from the forums, just do what they tell you to do about the break in that way you are covered.

Just make sure you get that oil change at 500 miles !!!!

Yes, Oil change will be done!!!

And... They told me don't keep it at a steady RPM for too long. That's what it is...
