The only way you are gonna make that is a MIRACLE!!!
It would take a MINIMUM of 1 hour assuming NO TRAFFIC by car and you are in your car (as opposed to being in the parking lot) to get from Met Life to JFK
By Public transport which might be faster considering traffic, Best case about 1 1/2 Hours
At least 30 mins train from Siyum to Penn Station, 30 mins LIRR train to Jamaica and another 10 mins airtrain from Jamaica to JFK (You have to add in wait times as well)
