anyone running a th400 hydramatic?

The only time I ever thought a GM trans behind a big block was a good idea was in one particular guys situation here at Bandimere. His 17 year old daughter was moving from one of those Briggs powered dragsters to a 10 sec 'Cuda. He thought that a powerglide would keep her from making mistakes as she'd only have to shift once and didn't have to think about what gear do a burnout in. I had to agree.
