Any small block pattern for will work for ya...either the 300 I-6, 302 or 351W is what ya need.

As for the flywheel....since it's a EFI 5.0 you need a 50 oz. imblalance....To get this you need to stick with the late model 5.0 or any year 351W and you'll be alright.

in 82 they switched to the one piece rear main seal and changed the imbalance from 28 - 50 oz. I also believe all 351W have a 28 oz imbalance. Make sure you know what year your motor is. Just because it's fuel injected don't ass-u-me anything.

I had a hell of a time finding a flywheel for my motor. Ended up getting one from Toms Bronco parts out of Oregon. Of course I needed the older 28 oz imbalance with 11" clutch.

If you infact do need a 50 oz, try to find one for and 11" clutch. They aren't as common, but you might as well get the big one.

The one out of an Early Bronco will work, but I suggest you take it to a machine shop with your pressure plate and have it match balanced. I did that with mine when I did the swap..It works perfect. Cost me like 125.00 bones though! <IMG SRC="smilies/biggrin.gif" border="0">

What slvrgl for got to mention is you need the stock fly wheel and they will match the balance to your new one. So if all you can find is a 10" clutch type you can use an early ford one and get it balanced right. I need to check but I might have both a new 10" and an old 11" I can check in the morning.
