Where do I locate I D # on 4 liter Jeep Motor
I have a 1982 CJ-5 258 and it's making lots of noise. So I picked up a 4 liter. I believe it is the same block. 1 Where do I locate I D # on 4 liter Jeep Motor to find out what year it was made? And will I have lots of problems swapping it in for mine? I know I have to change the water pump to fit my fan bolts. And have to run electric fuel pump mine was mechanical. Put my intake & exhaust manifolds on it, it had fuel injection originally on donor. Can you think of ant other problems?
