I recently bought a new one and discovered that with the engine bolted up to the block the converter would only move about an inch or so. After much cursing and backing the trans back I finally realized that the tabs on the converter were hitting the welds which hold the ring gear to the flexplate. On my previous unit I could turn the converter easily to line up the bolt holes. With the tabs hitting I had to line the converter up prior to bolting everything together.

I have two or three MP performance 8 bolt SFI plates, we don't run them anymore so if you want to try on of those PM me your address and I will give you one. poppaj 5916929-chev1.jpg (93 downloads)

Make that three of us, and I know there's more.... There was a run of B&M 8 bolt flexplates that had one of the converter bolt holes out by about 1/16" and one other hole out by just a hair.... you have to get one of these flexplates to believe it, but make sure you try the bolts through the holes and into the convertor before tossing your drivetrain in or together.... it will save you grief.

I had 4 or 5 of them crack around the flexplate holes, in 2 years. The holes are very close to the edge on the B&M flexplates.
