1952-59 Ford AOD Flexplate Question

Going to install a 351W & AOD.
Engine will be high compression (10 to 1).

Flexplates come in 157 or 164 teeth. Does it make a difference?

Also, engine will be "0" balanced. Do I need a special flexplate?

Thanks

 

Most 351W are 28 oz balance, so yes you would need this to be correct for a neutral balance http://www.kmjent.com/cart/164-tooth-small-block-ford-flexplate.html

 

I'm pretty sure all AOD flexplates were 164 tooth.

 

Hey, you guys are great.

I have a lot of parts to buy to make the swap, and that's what I'm working on.
Want the parts here when the engine arrives.
Now I also know what starter to buy!

Here is the engine, but I am also getting some options.

Again, thanks much guys,

The way I always understood it was 157 tooth fits the small bellhousing C4 and the 164 tooth was for the large bellhousing c4 and the AOD.

If I were you I would be getting it from the same engine builder so it is balanced properly with their ***y. This will eliminate any confusion.
