I have a marine power 5.7 vortec carbuerated engine. Bought in 2013. I'm trying to figure out if it's a GEN+ version or not. The reason is the intake manifold bolt torque for non GEN+ is 35 ft lbs and GEN+ is only 11 ft lbs. Don't want to damage my engine. Can someone let me know how to identify GEN+ as opposed to non GEN+?
Serial # is 50357
