If the person that did the swap used the parts that came with the 351, wouldn't likely already have 4 bolt balancer and passenger side timing mark?
Good Question.
260's, 289's, 302's, and the 351w through 69' used a passenger side lower radiator outlet on the water pump. The radiator outlet was also on the passenger side. The timing indicator was mounted on the driver's side and the harmonic balancer supported only 3 mounting bolts.
In 1970 things changed. From then on the 302 and the 351w both were changed to driver side radiator outlets at the water pump, driver's side radiator outlet, timing indicators were relocated to the passenger side, a new harmonic balancer that allowed you to read the timing on the passenger side, and that balancer was drilled for the new 4 bolt pulleys.
What makes things fun is that all of this stuff can be swapped with each other--sometimes with good results, sometimes with bad results BUT they all will fit. For example, my 89' 393W uses many parts from the original 65' 289. The timing cover, water pump, harmonic balancer (28 oz), and the 3 bolt pulleys work just fine.
It is best to swap all or nothing because of the problems I referred too in the above post.
You have to be carefull playing with the later 302's because Ford switched to 50oz balancing so you would have to continue using the newer balancer. On the otherhand, 351w's all remained 28oz--just like the 65' 289.
Soooooo, the original poster either has a 69' 351w OR someone did the same swap as I did using the earlier parts on a later engine.
