I am doing the same thing this winter. Having a c4 built for 87 AOD car, running 351W. You need a c4 with the large bellhousing and run the stock flywheel, as in my case with the AOD, but you need a converter with the large bolt pattern, 11 7/16. ( I think that is the correct one, but not the small 10.5 inch coverter bolt pattern. ) The late model 302 W are balanced with the large flywheel.
