727 Valve Body Disassembly Findings

The only difference between Ford and Chrysler aluminum valve body problems is that Chrysler went to a dacron filter, while Ford kept using the brass screen. My C4 builds all get an adapter to use a Chrysler dacron filter. They are then equal in their valve sticking problem. However, the th350 and th400 use steel valve bodies, and they are the most trouble free vbs out there I have seen, even with just screens. Some al vbs use aluminum valves as well; total disaster.
