1973 -400 -2-Bolt small block, dated A-18-73 , from a 73 Caprice. all stock and never been apart, other than when I pulled the pan to verify 2 bolt bottom end,( better than a 4 bolt). It is a #3951511 block casting with CSA code. Complete from 2 bbl. intake down to the stock balancer & oil pan.. Had not been run in years, but was filled to top with oil and turns over freely.Was pulled years ago as a good running engine, I ran it on my test stand for a few seconds this week, but oil is spewing out of the rear main seal. no noises.Mileage ? can't remember. selling as rebuildable core. very hard to find one all together that has not been jacked with anymore. I'm sure when I finally hurt my 400 block I'll be sorry I sold it ,but I need the floor space.$500.oo or will trade for smaller, sellable musclecar or hotrod parts, no junk. No I don't want to sell just the block. it goes complete. DAVE, 856-678-7883 before 9:30 PM. In Pennsville, N.J. only 5 minutes from base of Delaware Bridge. I'm quite capable of strapping securely to a pallet , for another $30, and delivering to a shipping depot in New Castle Delaware or Wilmington. There are quite few shipping companies over there. Shipping arrangements would be on you.
