Torque converters

The weak spot in the small block trans is usually the direct clutch pack. They usually only have three frictions; whereas the bb usually has four; hemi five. Most of the big bad 518s I've taken apart only had three as well. Any 727 converter will be strong enough.

Thanks for all your responses, it helped me out. With the prices coming down on some of these parts to replace stock ones, maybe I can get another 80hp or so. I figure that will get the results I want.
