Hello fellow enthusiasts! I'm trying to acquire a little info on this truck. This beauty is my girlfriends (lucky me). It's pretty much bone stock mechanically, 6V, 3 on the tree, floor start. I'm trying to determine the motor, I'm pretty sure the Canadian spec GMC had a Chevy motor, but of that I'm not sure. I have attached a couple of pics, one is the serial number on the block, the ID plate on the door and a pic of the old girl herself I did search for the motor info, but came up short Thanks,
