Using a flywheel with a 727 case might work and it might not. First it would have to be a small flywheel to fit in the 727 case. I'm sure an 11" wouldn't fit as their really big. Plus you have to use a 10-1/2" flywheel with a 10-1/2" bellhousing and a 11" flywheel with a 11" bellhousing or the starter won't line up. Haven't done and measurement comparisons of a torque converter against a flywheel's ring gear so I'm not sure. A 10-1/2" flywheel might work, just have to measure the ring gear against a torque converter and see if it'd physically fit in the 727 case.
