Human Factors; Procedure
Advised by ATC that there was traffic at 9 o'clock and identical altitude - transiting to the west/southwest. I was on a south/southwest heading. Neither aircraft initially located the other. No evasive direction was given by ATC. I noticed the conflicting traffic when it was 150 feet (or less?) at my 10:30 and crossing in front of me. We were on what could easily be described as a collision course. I took evasive action - diving right turn - and announced traffic in sight.
An IFR single engine aircraft pilot reported a near miss with another IFR aircraft at 8;000 feet after both aircraft were advised of the other but were unable to detect the other until 150 feet apart. ZNY provided no separation guidance to either IFR pilot.
