flexplate question?

he guys which flexplate do i need if i am using a AOD and a 351w? thanks guys.

If I'm not mistaking it should be the same one you used on your 302, Just make sure your using the right one as far as the teeth go, mine is with a c4 with a 164 tooth, and also that the balance wt is right for your app, such as 50oz, 28, or 0 (neutral)
