Balancer/Flywheel interchange

So I'm taking out the 351m in my f150 and installing a 400.

Can I use the harmonic balancer and flywheel from the 351 on the 400 or should I just buy a new set for the 400?

Technically they will work.
Have to inspect the condition of your balancer.
Very rarely there is a difference in the timing indicator, so check that to
make sure they look the same also.

Thanks. I'm going to have to use a sleeve kit on the original balancer. It's got a pretty good groove worn in it. Parts place can't get me a new one till next week but I need to get this thing back together.

If it's worn down to needing a sleeve then I'd look the rubber over real close for cracks too.
