Performs exactly as expected

September 11, 2010
If you have the option use the 164 tooth style as this moves started farther away from block and less grinding if any will be needed.Instructions have you bolt the flexplate to the crankshaft before mounting thin spacer plate. The spacer needs to go on first.
Pros:
  • Good Quality
  • Everything there
Yes, I recommend this product.

The bolt pattern would be the same whether you had the large or small bellhousing which dictated the flexplate diameter. The flexplates are the same but the torque converters determined which flexplate to use. If you have the smaller converter with 10 ½” bolt circle you need to specify the 157 flex plate and if you have the larger 11 ½ then you specify the 164 tooth flex plate.

This conversion kit comes with choice of flex plate in either 157 or 164 tooth depending on customers transmission and torque converter requirements. It is a special flexplate that works with the flathead crankshaft in combination with the appropriate converter. If a replacement is needed Speedway does carry the flex plate individually.
