Ford changed the balance in mid-82. Get one for the same year as your 351. Bear in mind that the starters and bellhousings changed in the mid-80's too, maybe the same time as the balance. The pilot hole for the starter is a different diameter.
1980 and later 302 or 5.0 use a 50 oz balance the 351 stayed 28 oz like earlier 302's,so you need to match them up,your flexplate is wrong.Quote:

thanks guys for the info.. i'm sure i got a older 302 laying around somewhere i can rob the flexplate off of..well that solves one problem..now on to the next one ..ha ha ha ha
i forgot to add that i am going to be using a 84 model ford aod transmission..as long as the tooth count is right it should be ok to use that trans ..right i hope :)
