I recently purchased a 1966 Ford Mustang for way under market value.  When I got it home, found the fuel pump was bad and needed replaced.  Then discovered original engine had been replaced.  I was hoping to ID the new engine.  It may be a Ford 170 inline 6 but the fuel pump doesn't match those of other fuel pumps.  Any help would beneficial.  Thank you.
