I have to take starter out to see that number. The one on the head and in front of distributor say it’s 261 motor. Trans is funny. Has pto on the side powering an aftermarket winch. Think it’s a Tulsa 18g maybe model 838. Might have a Frankenstein here. Front lugs are 5 bolt 6-1/4. Other trucks have 8 bolts. Do have 10 bolt rear.
