    Sad story with 66RivGS - sold it to someone in Europe and engine somehow seized during transport from US. I don't know exactly what happened, but looks like broke a rod trying to get it started and lower part of the block was damaged near the starter (see photo) - I doubt this block can be repaired but interested in repair options if anyone has ideas.

    Trying to help the new owner locate another, rebuild able 425ci block, because the original block looks damaged beyond repair in picture.

    Anyone have one and willing to sell it so I can ship to new owner?

    Thanks!

    I have a 66 425 block out of a Riviera .
    Machine work done and I think cam bearing in .
    Also have crank , heads, etc.
    I'll get pictures if you are interested
    Never shipped any thing like this before .

    The best thing you can do is try to find a complete running engine. You need a block, crank and at least one rod with the possibility that it may have gotten into the cam. A lot of risk with parts out of that engine. BTW, it looks like the rod bolt came out since it's missing. If the bearing had seized and it threw a rod the bolt would still be in there.

    The block is a MW 66 425 , New Cam bearing , looks like cylinders were honed , not cut .
    I have the crank , pistons , rods , intake , carb , dist , etc. , heads reworked but number looks to be 65 401, 425

    Bill,

    The block can be confirmed by looking at the stamping in front of the valley pan stamped in the flat area behind the water manifold on the right side, passenger, or your left looking at it standing in the front. A KT would be a '64/401 a KW would be a '64/425 or a KX would be a '64/425 2x4. A '65 would be the same except an "L". A '66 would be an "M". ALL second letters basically remaining the same. K-L-M.
    On the left is also the ID number. I know a 7 would be a Riv. Like on my '64 it starts with 7 K. meaning Riviera 1964.

    Hi Tom,
    The block is stamped MW , its the heads I'm not sure of . Numbers ( casting ) maybe different
    but I think heads, valve , springs etc are the same 64 -66 425's and maybe 401's ?????

    Hello-
    Thanks for the leads - checking with new owner to see what they prefer.

    In 5-10 years the broken block might be repaired with additive manufacturing - aka 3d printer

    We are right on the cusp of that aren't we? Spray welding may be an option too.

    Probably just as costly as getting another engine & who knows how long it will take for that technology to become available????
    You also have to remember what other unkown hidden damage may have been done. You have little or no idea of UNTIL you start screwing things together.
    Just my thoughts.

    I agree, if he is overseas a compete running engine would be a smart investment vs shipping another bare block

    Finding a complete and running 425NH engine is possible? Seems less likely than rebuildable?
