Need Help Identifying Motor.

Sep 24, 2017
So my pony has been down for a bit and she came with the 3.8l and t5 tranny, and I just got a v8 for free today, its only the block, pistons, and cam still in the motor, but it bolts right up to my t5 so im thinking its a 302 (5.0l) the only numbers on the motor are on the back of the block and it reads NNA65515. Any help would,be awesome as id love to put a 302 in my pony! Thanks in advance!!
