    PLEASE have a reputable machine shop verify that the crank is straight, the pistons are dimsionaly what they say they are, and that the balance is correct.

    One of my son's friends built a motor with a brand new "balanced" rotating assembly kit. Got it running and it had a vibration at 3500 to 4500 rpms. Took it apart, had a local machine shop check it and found that the crank was off 50 grams and bent!

    The bottom line is that those kits are only as good as the operator making them is.

    I am going to be doing an engine for a customer and he has a eagle kit so I will be checking it for the weight and it to be bent I will let you know later next week if I find out anything.

    And if it was a $5220.00 kit I'd expect you to do exactly the same.

    When I built my 468, I put a new Eagle crank and H-beam rods in it without any issues. Yes I took it to machine shop and they balanced everything.

    Re-using the stock parts is warranted for what you are doing.
    They'll last another 200k with proper oil changes, working cooling system etc before it will need refreshed again.
    If you are over boring, of course new pistons are warranted.
