1936  Flathead Ford used engine block, LB, for insert main bearings.

Part number 68-6010.  This block has been cleaned and magnetic particle inspected by three different shops with no cracks found.  It is the nicest 36 LB block that I have seen in decades. 

Bores are 3 1/16 +.030 with worst wear found .003", so it could be run at +.030, or honed to +.040 for fresh bores.  It would be best for you to come and examine the block before purchase and take it. 

There is a $100 crating charge to prepare for shipping. Shipping would require separate ship quote which we can provide if you email us your delivery address.  It would be truck freight, estimated weight after crating 230 lbs.  Or as above, come in and examine it and pick it up here.

I actually have two of these blocks now that are very buildable; the other has thin sleeves back to STD in all cylinders and is also crack free and very nice.
