Thanks guys!  Now,  Mike. Yes, a 390 Ford actually was designed originally for the marine industry.  But a boat Anchor?  Pffflllppp..... actually,  I think it breaks down like this and it clearly shows its nautical roots:
390 Ford Parts Weight Conversion Chart:
1.  Cylinder Heads:  Turrets from the Merrimack
2.  Intake Manifold:  16" Shell slug from the Missouri
3.  Water Pump:  Anchor chain from the Mauritania 
4.  Crankshaft:  Recycled propeller from the Bismarck 
I think that sums it up.......
Cheers

Dave
