Post subject:  Odd motor break-in question??

Now, this is not directly slant 6 related but it IS Mopar related so... please cut me some slack. :)

I have rebuilt a 318 to put in my 1966 Clark RV. I will have a break-in period that I am not sure will be very easy to manage in a small bus sized 9000 pound RV. I will do the cam break-in stuff then I have to seat the rings and drive the beast 500 miles...
I also live in the middle of Hollywood. Small streets and kind-of a distance from any freeway that has no traffic to seat the rings and do all that stuff.
I thought that I could have a few weeks of "after midnight driving" while there is no traffic to do this stuff ... OR ... I had another idea...

What if I took my rebuilt motor and put it in my 65 D100 for the break-in. It is much smaller and lighter than my RV, I already have the bell-housing that has the multiple bolt pattern to accept it, I already have an HEI set-up in my truck and my slant six said it wouldn't mind... ;)

Would there be any reason to not do this? I have heard conflicting theories about motors being broken-in in the vehicle they are meant for and others saying that it is a great idea. ??

I highly value the knowledge of the people on this board which is why I am asking. Thanks for anyone who might help me on this decision.

Frankly it is more of a space issue than anything else. Breaking-in a motor on my truck is much easier to fathom. Especially because my truck is MUCH more manageable in the middle of a city than my RV. And motor swapping into my truck is rather simple due to the nature of how the motor is mounted in my RV. So if there were a problem it would be much easier to pull the motor from my truck than my RV.
I also live on a street where I have no driveway and street cleaning twice a week so motor swapping on the street has to be pretty quick. lol

You sound like you've got it under control and so long as you slant is ok with it go for it :wink:

That is kinda what I was thinking. I figured it would be an easier break-in to do it in my truck than to make that new motor drag around 9000 pounds right off the bat also. lol

Any other advise from anyone? THANKS!!
