SFI Flexplates - 05/14/19 01:53 AM

Hey all:

What is your choice of an SFI rated flexplate?

The "cross" shape like an TCI, or the round style such as the B&M?

Bigger question, any issues with either.

Thanks in advance.

Every plate I have owned except a round B&M have been the MP ones..
the reason I had to use the B&M one was to make my engine balance
with it... all the others have MP

The MP is not SFI so I went with B&M up

Do you need a 6 bolt or an 8 bolt? I have a new 6 bolt B&M that I don't need so if you need one of those shoot me a PM.

The MP stock shaped SFI plates that I had are (were) solid without the cutouts. Had 7/16 holes already too IIRC.[Linked Image]

A few years ago I bought a SFI 440 source six bolt very nicely made looks just like a B&M I think I paid $39 for it

B&M had a bad batch of their neutral balanced 6 bolt flex plates that had one of the smaller diameter(11 inch) 7/16 converter holes off far enough that one bolt wouldn't go in with out work weld I had several racer friends who had that problem work
That being said I just took in a used one for trading some labor with a friend and customer, I hope it isn't one of the bad ones luck
