When i took my 351W to the machine shop and had all my work done i also had the entire motor balanced but when he balanced he used a stock flexplate that was being used with a FMX tranny. My question is do i need to purchase a stock flexplate or am i able to buy a Hi performance one for this application? Does it really matter about how many teeth it has?

As long as the harmonic balancer mathched the weight to the flexplate you will be okay, I mean it would be better if you would have given it to the at one time, but hey, and yes teeth count does matter.

 

Ok so will i be able to purchase a Ford Racing Flexplate as long as it has the same amout of teeth and as long as it is the proper weight?

you need a 164 tooth flexplate for your aod. a stock one has a 50oz imbalance if it was in a late model fi 302. if your 351 is 50oz this will work.

 

awesome thx
