LETS TALK FLYWHEELS
The 67-69 Big Block 4spd A bodies used a 130 tooth flywheel and a 10.5 bell housing as did the 70-74 B & E bodies with big blocks or Hemi....
There are original and aftermarket bell housings available to do this..
The 11" bell that uses the 143 tooth flywheel is bulkier, made of cast iron so it's heavy... And really just isn't necessary...
