727 rebuild stock/hp street

Where did Chrysler use stock components in their 727's ? Lets see, behind Hemi's, 440's, 383's, 340's, Max Wedges, plus a variety of ambulance/police/ truck applications. So my way of thinking for soft parts, would be to get a stock master kit, with Raybestos waffle lined friction plates, steel plates, both bands, a bushing kit, maybe a washer kit, filter, and the rear clutch return spring. And maybe the Transco small SKTF shift kit. There is nothing wrong with ordering a performance kit from Cope or others, if it is needed, but from your post what I've listed should be more than adequate. You may find other items you need once it's apart. Check and see if there is a Transtar warehouse nearby. Their main business is supplying transmission parts to transmission shops.
