I recently put a pi engine in my 96 automatic. I have a 4r70w behind it. The engine is a windsor with an 8 bolt crank. No one seems to make an 8 hole flexplate to accommodate the stock torque converter (10.625" bolt pattern) so I decided to replace the tc with one that a 8 bolt 164 tooth 11.44 bolt pattern will fit. Any good recommendations for a torque converter or do you know anyone who makes a flexplate that will fit the stock converter. Car is a daily driver with maybe 300 hp. Thanks.

Or you could get a flex plate from a salvage yard 1999-2000 automatic Mustang. Try searching car-part.com

I had an aftermarket torque converter rated at 2400 stall. I used that same converter with my stock flex plate and with an 8 bolt flex plate.

Got everything together and the car runs pretty good. There is still a slight shimmy at about 3K rpm. Converter and flexplate lined up perfectly. I pulled the dust cover and the flexplate seems to have a little wobble which I suspect is my shimmy. Is there a proper way to clock it? I googled it but nothing came up about it. Only thing I can figure at this point is the flexplate is no good. Any suggestions?
