Which starter & flywheel to use?

I'm installing a '87 351w....I was wondering which starter & flywheel do I use the I6 cyclinder starter & flywheel or a 351w starter & flywheel?

 

Im not familiar w/ I6 stuff, but I know you need to use the correct flywheel for the motor and bellhousing.

This goes by weight and teeth for the flywheel.

 

The I6 flywheel/flexplate might bolt up, but it is the wrong balance.
So, no... the I6 flywheel/flexplate won't work.

The starter will continue to work fine if that is the bellhousing it came from.
The flywheel/flexplate needs to be a 28 oz flywheel/flexplate with the same tooth count as the I6 one, again assuming you are using the I6 bell.

*Flywheels are used on manual tranny, flexplate on autos.

Now, if you are using a different bell than what was on the I6, then that could change the whole equation.

 

The 250 and 351 use the same starter. The 200 is a different part number

 

I thought 87's were 50 oz imbalance? Or is that only on 85 up 302's?

 

All 351s were 28 oz.
Only the 302 went 50 oz... believe it was in 82.

 

Correctamundo................. The actual changeover date though is even a mystery to Ford. It was sometime in the 81 to 82 model years.
