I have what I think is the small bellhousing C4 and am wondering if both size flexplates will work or if I need the 157 tooth flexplate. I have a 164 tooth. I also recently bought a converter for the 164 tooth, so I hope it will work. Any help would be very helpful.

 

if your flywheel is larger then you will have to use a bellhousing that
takes a flywheel that size, there are at least 2-3 different v8 housing
good luck finding the matching one you need.......................

 

The c-4 bell housing are removable though they are differant besides being big or small ,they bolt up differant depends on if its case filled or pan filled, stuff like that.TCI i found is the best and cheapest way to get what your after ,flexplate and bell housing would run about 200.00 or you can check your local pick-n-pull. look through summits or jegs online catolog for what you need
