TH400 for sure. ......At that HP I'd use a Vasco input from ATI or the supplier of your choice. .....Also, ATI has a center support that has a bearing to support the direct drum,which improves both ring sealing and sprag life. ....All the rest of the parts will live at that HP,altho I'd also use an aluminum direct drum , for a little added safety. ......I have a customer running a nostalga Gasser with a 1100 HP blown Hemi with this setup with no problems for over 3 years. ......Tom
