    Help with rods and crank.

    Can anybody tell me which rods are these? Also the crank.
    The right one is the one I need to know which one it is. The left its a new set of eagle, 6.125 with 2000 bolts which will be use on another engine. The other one has the L19 bolts and this ones are used.





    This is the only pic I got of the crank, all I know that it is forged and 3.622(stock) stroke. Which will be use with the unknow rods.

    bolts say Eagle on them, could they be eagle rods?

    Crank looks like a reman. Has company name and reman serial code with 3.622 stroke stenciled on it. I have never seen that on a stock unit.

    The rod on the left uses a bushing where the pin in the piston goes in, and I think the other doesn't?
    The rod on the right is stronger than the one on the left The L19 bolt is larger than the 2000 bolt.
    The crank looks like a standard forged eagle crank.
    The rod on the right goes for 500.oo and the one on the left goes for 270ish?

    Oh and the crank. I took it to a shop to compare it with a Lunati billet crank and they were very similar, but it was a longer stroke, and compare to my eagle 4" stroke, they don't look the same in detail.
