Here is a crankshaft as shown.  This was out of a 351M engine that had a 2 barrel carburetor and was out of a 1978 Ford F150 truck.  I could not find the marking on it for ID, but did pull it out of that motor myself.  I did not see any spun bearings or anything like that with this crankshaft.  This one appears to be standard currently, but it does show some wear, so it may need turned.  I'm not sure, I'm not a machinist.  SOLD AS IS AS SHOWN ONLY AS A CORE FOR REMANUFACTURE.  It will need a good cleaning and going through before use.  These are VERY VERY dirty and greasy as shown and will be shipped that way.  NO RETURNS.

Determine fitment based on the part number only, go with what you think based on the part number and pictures, not what I have in the title.  Make sure that you have the setup that will require this intake BEFORE you purchase.  There are no returns, so ask any questions you have and do research BEFORE you purchase.  It may show some wear, rust, and may be dirty; see the pictures.  It could use a good cleaning and maybe some paint to look its best.  I'll be happy to answer any questions that you may have.  Feel free to make an offer.  

All of these items may have scratches, nicks, could be dirty, etc.  Use the pictures to judge condition farther.  Sold as is.  Shipping is to the lower 48 states only.  I will answer all questions.  I take feedback seriously.  Please leave me good positive feedback and I will do the same for you.  Check out my other listings!
